2 weeks ago I had Wal-Mart change my oil before I went on a trip towing my Toy_hauler. While I was going up a VERY steep grade I spiked the temp to 232°. The check engine engine light came on. While I was on Vac the "Check engine light" went off but then the warning center message was saying "Change engine oil". I only put on 750miles since the oil change. The oil put in the ride was Rotella 5W40. Can any of you offer me any suggestions apart from the obvious, "change your oil". Should I get the oil changed or what??

They didnt reset the "oil change" metter. Its in your manual. Since you just did it and only have 750 miles on it, I would just reset it and change your oil at your desired mileage (3000, 5000, 7500, 10000...??).


LATER!

do you have the computer that shows oil life...i do, you probably jsut need to reset it how many miles you have on your oil? go at LEAST 3000 otherwise your wasting your money

Beat ya to the punch JhnZ71. :ro)


LATER!

There right about resetting your oil reminder, but you should have the computer scanned to see what the check engine light was about.

Might of been over temp code or something like that.

If you notice your truck starting to get that hot you should really let off a little bit to keep temps in check till you get over the hill.

for a 2002 you turn the ignition to the "ON" position and push the throttle down 3 times within 5 secs. Sometimes you have to do this a couple of times before it clears.

Thanks. I will try that.

I would be more concerned why the water temp went to 232. That is not normal under any circumstance. Later! Frank

Watch what kind of oil filters Walmart uses on your truck. They like to use Fram oil filters at the one near where I live.-:t

From past experience I would NOT recomend using discount Oil Changes. Read the labels at Walmart made in China. Use a reputable Oil Change facility.

I hope they did not put 5w-40 in your truck. It is suppose to be 15w-40.

Tom

Could be 5w-40 synthetic which is perfectly acceptable.

I would tend to agree with the sentiment of not taking it to Walmart for oil changes. Personally, I wouldn't take a Honda there for an oil change, let alone a diesel.

I agree with habanero...the only grade of oil that i have seen 5w-40 comes in synthetic.

202-210 degrees fan is fully engage,220-230 warning on dic at this point you can slow down or drop to lower gear to rev engine rpm for better air flow from fan.my frightliner kills the engine after second warning at 265 degrees and yea it only happend once!

CHOPJAW,


Just curious as to what was your oil pressure was when the temp got up? What was the ambient temp?


Gary

Could be 5w-40 synthetic which is perfectly acceptable.

Even if you live in the desert southwest????





Gary

I believe that the oil the dealership puts into d-max's is Delvac1 (Mobil diesel synthetic) and it only comes in 5W40. I run RotellaT Synthetic ($14 a gallon instead of $25 a gallon for the Delvac1) and it also comes in 5W40. Warm oil pressure is ~60psi at hwy speeds and ~30 at idle.

I would have bet on them having "Put in the usual 5 quarts, right Joe ?"
as well as not resetting the oil life reminder thang.

BTW, I was wondering about this a couple of months ago:
Is there any record of resets and mileage kept on the vehicle ?
i.e. can a GM tech scan the on board computer(s) and say, "Hey, you went over the oil change interval a coupla times, no warranty for YOU Jimmie boy". ?

Just my paranoia, it may not be Big Brother, but the little (tran)sisters that watch over us.

Many diesel fanatics have not learned that products are not better just because of high price and hype! Fishing lures "must" catch fisherman, not fish to make their seller money! Many will use anything as long as it costs more money and then "imagine" a great benefit in a placebo affect! Any good scientist will tell you that you can't accurately compare oils without controlled tests! There are too many other variables that affect your truck to really know! Believing in something without prove is called a religion! Stick to things that are proven by science when it comes to diesels or you'll wind up falling for every unproven hype!

(Dear Diesel Fanatics, I invented a device on that decreases your fuel usuage by 10%! If you put 10 of them on in line your fuel tank will stay full when you drive! Please don't put on 11 or your tank will overflow! Send me a Gazillion Dollars for 10!)

All kidding aside, I've used Walmart Super Tech 15-40 oil and standard filters for over 100K miles on 3 different trucks with great results! It's got all the same API Service seals and is approved by Cummins and Allison, and other diesel engine manufacturers! The issue is changing oil regularly to keep corrosive blowby elements out ot the oil, not buying "super oils" based on hype! My problem is what to do with the money I save by not buying every hyped additive on the market!

Dave, keep saving that money as you will eventually need it for parts if you keep the truck! LOL

To each his own, but my "religion" is Mobil Delvac 1 and the AC Delco OEM oil Filters. As for facts, that has been presented here numerious times along with lab test results. As to the filters all you have to do is cut open a Fram and case closed. Wal-Mart is well know and successful for selling cheap and inexpensive items. Some of those items are brand names that they get a deep discount on due to buying power from volume, others are just cheap items that may or may not last as long as a brand name same item. I do shop there, I will admit it, but when it comes to oil and filters, I don't know who makes the Tech line for them, but I am sure even if it was Fram, the Tech line more than likely doesn't have the same spec and quality control of even the Fram line which is very poor in my opinion. Anyway, far be it for me to tell you what to do with your truck, but in life you always get what you pay for, every time. Your goal with the truck is the key, if you don't plan on keeping it forever then Cheap is one way to go and let the next owner worry about it....if you plan on keeping it a long, long time, then the better you take care of it the longer it "should" last. Key word is should, there are always exceptions. Some guys take good care of themselves and eat right, exercise etc. and die at 48, others eat too much, drink and smoke and live life hard and live into their 80's and 90's before departing this planet.

Bottom Line is no one knows the future, we just do the best we can, but I still think my truck will outlast your truck LOL

Live Long, Prosper, have fun and get naked often!

Good luck with all that........I'll stick to Rotella, have run it in every diesel I have owned for the last 10 years, no problems.

I personally don't trust very many people to change my oil. To many people out there who don't GAF!!!!-:t So I change my own, on Everything...

How much are you saving per qt of oil?

To me peace of mind goes ALLOOOONNNNGGGG way...

To Chevysrus,

I appreciate your reply and opinion! The basic thing I see differently is included in your statement, "In life you always get what you pay for, every time!" What color is the sky in your world? LOL! Just kidding! But that's one of those statements that sounds good until you think about it! Very often you don't get value for the money you pay, and then once in a great, great while you actually get more value than you payed for! Have you never gotten taken on a purchase, payed good money for what later turned out to be junk? Have you never found a deal where you got something far below its real market value, and still think it was a great deal today? I once carpeted a house for a single mother with three kids that worked two jobs for exactly the wholesale cost of the material because that's all she could afford! She wouldn't agree with you!

I've been involved with enough products on the distribution level to know that justs isn't true! Pricing for many products may reflect cost of production/quality or simply marketing strategy! Remington ammunition was marketed for years at a substantially higher price than Peters although they were the same product! Discount gasoline was considered inferior until people followed the truck from Joe's Cheapy gas to the Arco station with the higher price! Walmart 15-40 diesel oil is made by Valvoline and has the same ratings as the higher priced oils! I can't speak to Fram filter quality, but OEM Cummins/Dodge/Ford oil filters are "exactly the same filter" as Fleetguard only Fleetguard is about 1/3rd the price as the ones you buy from the dealers! As a young guy in college I worked at Ward's. An executive of a tool company told me that they were forced to produce three levels of electric drills because if they made just the one top quality drill many people would not believe it was better unless they saw a lesser model in that brand! He also added if all the drills they made were the top quality model, it would cost less to produce than the bottom quality model but sales would suffer! Bottom line is it's hard to know if a product is better, or we've just fallen for a marketing approach to justify a much higher price! In terms of motor oil, I don't believe the is a substantial difference between the super duper hyped oils and oils with the same API service ratings! Walmart Super Tech oil meets the requirements of Allison, Cummins, Mack, etc.! Paying less for oil allows me to change it a shorter intervals which I think protects your engine more than buying super duper highly advertised and hyped oils! The chemical pollutants that pass by the best of rings are the real causes of oil deterioration! They collect in any and all oils even if you pay $100. per quart!

Remember when you say,"my "religion" is Mobil Delvac 1 and the AC Delco OEM oil Filters", that religion is believing in something on faith without being able to prove it, or sometimes even understand it! That's why no one will ever change another person's religious beliefs! They are based on faith, not fact, so there are no facts to evaluate or dissprove! In saying that, I can't prove to you what I believe either! Without controlled testing, there are too many variables to know what causes your truck to run or last better than mine! We all have to just make our "best guesses" on theory and common sense, but don't fall for the hype of the company that makes the fishing lure! You can't even trust the fish! The best day I ever had fishing I lost my bait and caught a limit of trout with Fritos on a bare hook! When they biting they're biting, when they're not, they're not!

Be happy, and make your friend the President get his oil companies and Saudi friends to stop gouging us for diesel fuel! Watch the oil company profits!

Dave you never answered my question, how much are you saving by using Walmart oil....

I don't recall a big campain to hype oil for diesels, the only thing I see hyped is Car & SUV synthetic. Not really sure where you are getting that from....

Sorry I missed your question! I really haven't calculated the exact cost of Walmart Super Tech 15-40! I do my own servicing more as a matter of safety than to save every nickel! I have had some bad experiences with guys on the lube rack! I buy a two gallon container and two quarts for an oil change! I believe I paid approx. $1.20 per quart that way, but I think the price just went up a little!

In terms of hype for super oils and additives, most of it is among diesel enthusiasts! Many are deep into a hobby and want to do more, spend more, and bolt on more! That's fine, but I think many of them do so more on hobby enthusiasm than proveable fact! It's not possible to support many of the conclusions they make without extremely expensive, long term controlled tests which are rarely made! Most of the food suplements people are taking for their health today have no scientific proof behind them, but believers spend billions on them everyday! Hell, no one in this country even asks why we're building 14 permanent bases in Iraq if we're leaving! I guess for the Iraqi Space Program to Mars!

Most people do what they feel comfortable with and then think of the reasons!

My only point is that paying more, is sometimes just paying more! I don't know that I'm right, my wife finds me wrong a number of times an hour!

So if you are using "cheaper" oil and changing more often, what are you gaining?

I change every 7500 and don't worry about changing at 3k-5k miles.

Just an observation..........

Well changing oil every 7500 is certainly an advantage! I don't look forward to changing oil! I assume you are using a synthetic. The only reason I don't do that is that I believe that the chemical pollutants that pass by the best of rings are the real cause of oil deterioration! If oil is in a closed system like a transmission it has a long life! The corrosive pollutants of burning fuel get into synthetic oil also! I also don't feel comfortable with 5-40 oils! If money was no option, I have my personal mechanic on my estate change synthetic every 4k miles! I do run synthetic in my Allison and in my generators! I think that makes sense! If I trusted synthetic for 7500 miles, I'd be happy to pay the cost of the oil!

AV Dave,

Just an FYI for you. Walmart's oil is NOT necssarily manufactured by Valvoline. When I wrote an email last year and asked that question they replied it was being supplied from Havoline at that time AND it goes out to bid periodically for the best price from various manufacturers.

Interesting! I would expect that from any house branded type product! My only concern would be that it meets API Service ratings! I guess the base issue is whether another 15-40 diesel service type oil is substantially superior than another and will provide some extra benefit. I'm sure if the Walmart chain contracted to put "your oil of choice" on every Walmart shelf in a plain wrapper two gallon container the price would likely be less! I'm not sure that makes it an inferior product! A bag of Lay's potato chips was $4.49 at Albertson's while the same bag was $2.00 a Walmart! I have no stock or interest in Walmart, but with "some of their house branded generic products" they actually seem to pass alot of their savings of scale on to the customer! I put about 160k on my Dodge Cummins with not one engine repair on Walmart 15-40 oil before I sold it! When I sold it was getting 21 MPG and running better than when it was new! My '02 Duramax has had 8 repairs in 50k miles on the same oil! So what does that all mean? Beats me! As a retired science teacher I'd make the argument that without controlled testing, there are too many variables to know what causes your truck to run or last better than mine! The only thing for sure is that if you charge more you'd better claim to give more value!

A few years ago a company did a double blind taste test on bottled waters. The definite, overwhelming winner for best taste was New York City Municipal tap water! Do you think any of the people who buy expensive bottled waters would have come to that choice if the bottles of water had been labeled? My truck always seems to run better when it's washed and waxed too! It's called being human! Who knows the answers, not me? If I had any proof, I'd pass it along! Just another way of looking at things!

ptdiver,

Everybody should do what makes them feel comfortable, but Walmart oil is made in the U.S by major refineries with the same API ratings (not in China)! Been to China lately? I have! We used to make fun of Japanese quality too! I wonder what country developed the Duramax? I change the oil myself and service it myself! My experience has been that the expense of most oils is more marketing and advertising than superior quality! I have one vehicle in the family with over 300k miles on Walmart oil and Fram filters and it burns no oil and runs as good as when it was new! Buy a Dodge Mopar or Cummins oil or fuel filter and check the high price for quality! Then buy a Cheapy Fleetguard filter at about 1/3rd the price! Ford owns Fleetguard which makes the filter for Cummins and Dodge! It's all the same product marketed for different buyers at different prices! Remington and Peters were the exactly same ammunition, but Peters is marketed at a lower price for the discount trade! Sometimes paying more gets you more, but sometimes it's just paying more!
