The engines dont seem to be all that great so why bother with the added expense.

My injectors were going bad by 45-50k. My oil pressure has been continually dropping since new (dealers answer--> dont use synthetic).

So why bother doing all this. The trucks are not going to last ANY longer. Your injectors wont last longer. Plenty of people here use NO additives and regualr oil and have had NO problems.

I wont be using either one ever again till the day I dump this truck.

I actually think that the Emulsifying additive caused my injectors to fail. But thats just my opinion and we know how that turned out on the whole Uni fiasco. :)

That very well could have been a part of the problem. GM recommends only DEmulsifying additives like Racor or Stanadyne.

I know you didn't have good experience with it, but it's better to get the water to drop out of the system ahead of the filter rather than emulsify it, have it pass through, and effectively sand-blast your injectors.

I felt the same way about synthetic oil. Although not everyone has had the same experience, my oil pressure was lower. I figured I can just stick with dino and change it more often for the same price. For better or worse I do use stynadyne and red line with the fuel. My engine seems to run good but I only have 43K on it now. We'll see how it holds up. Hope the next pick works out better for you PC.....Bill

What is all this fixation with oil pressure? Lower pressure equals more FLOW. I am running Mobil 1 T&SUV, and my oil pressure is the same as it was with the Delvac 1300 15W40. Dang, some of you guys are such worry warts!

True enough, but some of the worry is founded. Low oil pressure can be a sign of fuel in oil and if the pressure drops too low this can lead to an insufficient amount of oil film between hard parts, either because viscosity is to low or not enough oil getting to all the nooks & crannies, either way it can cause wear and metal particles to get into the system. That's my $.02 worth. I use Rotella 15w-40 and change at 5000 miles, and Rotella Syn in the winter.

problemchild, I think you should just dump your truck and get something you like. The money you loose is worth all the stress it seams to cause you.

I just did the math...

I added up EVERYTHING I have spent on this truck in 30 months. It is a grand total of 45,000 dollars. Thats including its current value of 17k for trade in. At 77k miles thats $1500.00 month or .59 cents per mile to drive it.

And do you think it matters what I buy?

My last 4 trucks have fallen apart. Toyota/bad, Ford/bad, Chevy/bad, GM/bad

Well it looks like you have narrowed the field down to a skate board that way you are the motor and if you break down you will have no one to blame but yourself. Also the cost per mile shouldn't be to bad if you buy cheap shoes. Smile it relieves stress. LOL

Well, geez, I've gotten great service out of my truck - still running 19 mpg on the original injectors and here's my math:

Total Payout:$84,209.98Avg. $/Mile:$0.71Avg.$/Day:$53.40

So, you're paying less than me and I'm a happy camper.

Problem child, I'm a professional engineer. In my career I have found it helpful to notice patterns (of all kinds) to see if any commonalities exist.
Here's an example: "My last 4 trucks have fallen apart. Toyota/bad, Ford/bad, Chevy/bad, GM/bad." The common variable present is YOU!!!
You (and your driving environment) obviously destroy your trucks. There are many factors that effect car/truck life. The number one way to destroy ANY vehicle is driving style. NOT maintenance. You can change your fluids and filter EVERY day, but if you:
1. constantly accelerate and brake hard (Lead foot)
2. drive hard before the engine and transmission have reached normal
operation temps.
3. Don't allow the engine to idle and cool down after sustained pulling of heavy loads.
4. Payload/towing overload
None of your vehicles are going to last you.
My 2002 2500 HD D/A 4x4 has 65,000 miles and I just replaced my 1st set of tires and 2 new batteries. Other than fluid and filter changes, I haven't spent any money on repairs/replacement parts.
My 1994 Ford Ranger 4.0L 4x4 154,000 mi when I sold it, I put one set of tires on it (for free, Firestone replacements) and one set of front brake pads. That's it. Original battery, clutch, EVERY thing else original. Never added 1 drop of oil, other than 5000 mile oil changes.
My wifes 1995 Ford Taurus SHO had 172,000 miles on it when we sold it, I replaced the starter (twice) and one set of front brake pads. That's it. I talked to the guy I sold it to about 3 months ago and he said the engine threw a rod....at 293,000 miles!
My 1st vehicle was a brand new 1985 Toyota 4x4 pickup, 22R engine, my parents bought for me. I drove it all through my college years and sold it when graduated and I got married. 158,000 miles and one starter, one clutch, two sets of tires, 1 battery later I sold it for $5000. My dad only paid $8500 for it BRAND NEW!!!
What's my point? Point is I know how to take care of a car and truck. I know how to drive a vehicle in such a way that they last a long time and are trouble free.
I 100% sure the problem has not been your trucks, I think the problem is YOU!

I see in your post that you said:"Toyota/bad, Ford/bad, Chevy/bad, GM/bad"

First problem is you are on a very opinionated and PRO Duramax Forum, do not think you will be given any slack for any anti-max problems for that matter, but you do have a point, too many things to list with this diesel, there are lot's on here that help each other with these issues.

I did notice that you did not show Dodge in your list of bad vehicles owned....
I think a Cummins will be in your future.....
You have absolutly nothing to loose in changing.....
Except a better nights sleep.....

Never met a truck I didn't like

Problem Child:

I have never owned a bad vehicle, just ones I did not like.

70 GMC 3/4T-100K miles, never went into shop, excellent truck.

80 Toyota PU- 180K miles, excellent truck, changed air in tires.

82 Chevy C2500 6.2L Diesel-155K miles, injector pump (warrenty) & vacum pump. Good truck

91 Chevy K1500: 247K miles, Excellent truck- new Tranny @187K but towed too much, my fault. Engine used 1 qt oil every 3K miles new, and after 247K miles, used 1 qt oil every 3K miles. Changed oil every 3K miles.

2000 Chevy K1500- 88K miles, sold with original tires but were getting below the safe limit.

Current vehicle: 2004 GMC D/A-59K miles, stock, runs like a champ, change oil every 3K-4K miles.

Disliked: 78 Chevette, but who wouldn't?

His handle explains it all. He is the type of person to [email protected] at the dealer for EVERY problem on his vehicle. I hated people like that when I was writing service. IT IS MECHANICAL AND GOING TO BREAK!! DRIVE THE DAM THING AN SHUT UP!!!

I think I am going to start giving away oil temp gauges.
That would be an education.

Who would NOT use synthetic if they saw 300+ degree oil temps? I'm just curious. Anybody?

What can I say?

Anyone that wants to trade your "good never had a problem" running truck for mine just pm me.


No takers?

And if you think its all "my fault" or I "drive them hard" or I should stop "complaining" then I have one thing to say............................

people like you who have access to SI is also a problem. You start seeing all of the TSB's out there and start to freak out. Is that happening to my truck? Better get it in to check and then be a pain in the A$$ to the dealer since you have a GRIPE list with TSB #'s. It is in your head. Like stated earlier, go to another dealer and have them check it out and do not mention synthetic oil. If they are blaming it on the oil then call exxon/mobil and tell them what is happening and that GM is blaming the oil for your problem. Exxon will start raising hell with GM because GM uses it on a TON of vehilces right from the FACOTRY!!! OIL IS NOT THE PROBLEM!
