I have been driving for about 55 years...
In that time I have driven over 2,000,000 miles.
I have always had some type of automobile, be it a car, pickup truck, van, whatever...
Some of them I have put well over 100,000 miles on them... a few of the work vehicles went for 200,000+.
For a number of years I owned a diesel big rig in addition to the regular cars.
I spent several years with a lot of my weekends at the drag strip.
I have owned several dirt track cars at various times.
In that time, I have used just about every kind of oil you can imagine.
Conventional DINO oil, oil that is for diesel trucks only, synthetic oil and on and on and on...
In all that time and all those miles, I have had very, very few problems that could, even remotely, be attributed to the oil not doing it job...
I have always believed that if you change the oil regularly, you won't have many... IF ANY... oil related problems.
55 years later... it is still working that way for me.
As long os it is slick and slippery and getting pumped thru the engine... it is lubricating the moving parts.
That's all "ANY" oil can do...
I guess the debate will have to be... does one do it better than another???
Can one do it well enough to get 400,000 miles out of the engine and can another one do it well enough to get 500,000 miles out of the engine..
I don't know about y'all... but I don't plan on keeping mine long enough to see 400,000 or 500,000 miles out of it.
So far, my 2006 DTS has almost 122,000 on it and uses no oil at all.
It started out on regular DINO oil, but at about the the 3rd oil change, at around 12,000 miles, I switched to Synthetic...
A couple of times since then, it has had DINO oil put in it when it was changed...
Except for a very slight loss of MPG and a very slight loss of "SNAP" to the engine... I can tell no difference between one or the other...
That's my story and I am sticking to it...:cool2: :histeric: :cool2:
