Sorry, but that isn't my experience. Both of my Chrysler minivans like 35 PSI just fine and my K1500 likes 50 PSI just fine, except I do lower the rears to 40 PSI when the truck is empty. 


Damn, Matt!!

Just a week or so ago, you were arguing with me when I suggested going outside the manufacturer's recommendations on oil viscosity - after all - how could I know more than the engineers who designed it? But now you want to go outside the mfgr.'s recommendations on tire pressure.

I'd have to go back and re-read my posts to be sure, but I don't think that is what I said. I said that I didn't think that staying WITHIN the manufacturer's recommendation of 5W-30 viscosity oil would shorten your engine life. I don't think I said anything about not using oil outside that range. Personally, I don't for the simple reason that an engine is an expensive component to experiment with, whereas tires are relatively cheap. I can get fairly good tires for my van for less than $400 a set and even if my experiment increases my wear by 25%, I'm only out a hundred bucks or so. For me, that is a reasonably amount to risk on an experiment. The cost of replacing an engine isn't within my range personal range! :-)

Although, I am experimenting now with my 96 minivan. At the 150K mark I decided to switch from 5K oil change intervals to 10K, still using Mobil 1. The van owes me nothing so it is now within my experimental range! :-)

I did the same with a 79 Chevette when it reached 100K miles. I'd used Mobil 1 (actually Delvac 1) since 50K when I bought it from my parents. I really didn't care if I ruined it after 100K (actually was kind of hoping it would die!), so I decided to go 10K between changes. I sold that car with something like 130K on it and the person that bought it wrecked it just shy of 150K and the engine was still going strong.

So far, my minivan is doing the same and is just about to roll over 170K.


What the hell's wrong with you!!?? 8^) 

I'm an engineer.  I can't help it!  :-)
