What does PU stand for?

I'd really like to know, because I'm paying nearly $6 a qt for what I believe is true PAO based synthetic. I use the 5w-30 in my car and the 15w-50 in my bike. My feeling is that if Mobil One has changed over to a Group III oil, then I'll stop buying it, and look for a less expensive oil. I...

I'm not talking about heat treating. I am talking about relieving stresses built up in parts from the machining processes (stamp, cut, grind etc) that can make them want to bend or warp when heated. Heat treating refers to surface hardening, which is a whole other animal, and yes they are...

Originally Posted By: BerndV Pads and rotors that are designed to create friction are not a very good analogy. Neither is a high speed buffer which, again, is designed to create friction. My results, which you fail to address, far surpass simply not blowing-up. I fail to address your results...

Next time you polish your car, take a high speed buffer and run it up to top speed, and then press it against the paint as hard as you can, and see what kind of results you get.

It is the bedding in of two surfaces to each other, much like brake pads bed into rotors. The high spots wear down and both surfaces polish each other out. This is best done under light loading conditions to prevent hot spots and glazing, just like when you bed in brake pads. The notion that...

Well, I guess I was hoping someone had a white paper on the subject or some real research. Interestingly, Honda tells owners NOT to change the oil in an Accord until 8k miles are on the car. Not even to to dino oil. They want you to leave the factory oil in for the first full 8K. Which just...

I'm just curious if there is any information on this site that provides definitive answers to the question of when to switch to a synthetic oil in a new vehicle. Yes I know some cars come from the factory with synthetic, but many do not, and I continue to hear conflicting advice on this topic...

I think I found it. http://neptune.spacebears.com/cars/stories/mobil1.html http://neptune.spacebears.com/cars/stories/oil-life.html

I can't find the link right now, but I remember a published report by a guy who used a late model Camaro and did several oil changes at around 7K or so, and sent samples off to Blackstone labs, and then repeated the test, only changing oil at 3K, and the results seemed to bear out that there was...

I could accept 5K miles, but I frequently see recommendations of 10-15K miles, which I find unbelievable.
