I need some advice. I was at the Firestone dealer and he offered me an oil change for $47.89. That included the oil 15-40W and filter. That seemed low to me, but is that oil any good?

If its one of their diesel oils such as Super D3, SHP or DXA I would use it. I've had quite a few gaser engines with high mileage that were driven hard (muscle cars driven like muscle cars) apart and they were very clean with very little wear, can't say that about alot engines that used other brands of "quality oils" that I've been into, I'm sure thier diesel oils are the same quality, of course that is JMHO and personal experience. So thats my $.02 worth.

Don't know if they still do but the local Cigarette dealer used to swear by Kendall oil and used it in offshore engines costing $30k including the engines in their own race boat.

I was (retired jan. 04) a fleet mechanic / foreman for Niagra Mohawk / National Grid power company. We used Kendall 15w40 in all our trucks both gas and diesel. With over 1000 pieces of equipment in our area alone including backhoes, dozers, trenchers, etc. we did not experienced any engine failures in over 20 yrs that we used Kendall. We did have a good PM program that included oil and filter changes at 3000 miles plus oil analysis every 12 months. The mechanics in the shop including myself used Kendall oil in our own personal vehicles as well.................George H

Kendall isn't the same oil it was. It has been passed around between owning companies like a hot potato and the quality has been affected.

No doubt it has been a good oil in the past. Since the changes, they can't hang with the newer oils that have evolved. The additives tend to "Fall Out" reducing the life expectancy of the oil. At a 3,000 mile oil change no problem, but trucks running 20,000 it will be a problem.

My buddy has run Kendall 15w40 in all his trucks/tractors/semi's as long as I have know him, no problems yet. I run Rotella, but thats because I don't get my oil in 55 gallon drums like he does I just get the 2.5 gallon jug at TSC for $26.
