We've seen enough good UOAs on this stuff to prove that it's definitely one of the best OTC dino oils going. IMO, if you use this oil and do 3-4k oil change intervals, you'll get extremely good engine life.

If you actually try some other software alternatives that are innovating rather than marketing, you'll see exactly where Microsoft is lacking. But I digress.
Some people say Microsoft makes junk software and they bash the company, even though it is used on 95%+ of computers and is the most successful software company in the history of the world.
quote:The four big oil additive package makers are Chevron-Oronite, Lubrizol, Ethyl, and Infinium. Lubrizol and Ethyl are independent, and Infinium is jointly owned by ExxonMobil and Royal Dutch/Shell. The current owner of Pennzoil/Quaker St. is...Royal Dutch/Shell. Ken
Originally posted by Mystic: ... Chevron has the resources to develop its own base oils and its own additives. I think this may make a difference. According to what some at this site have found out, there are only a few chemical additive manufacturers for additives in motor oils. ExxonMobil and Chevron are some of the few. If some company is producing motor oils but getting its base srocks from some other company and its chemical additives from another company, that company may have a harder time creating a good motor oil. But if a company can manufacture its own base stocks and its own additives, that company may be able to make a better product. Does that make sense?
quote:What was the vintage of the Havoline?...up to 1998, Havoline was a Texaco product. From '98 to 2002, Havoline was a product of Equilon (a Texaco/Shell venture). After 2002, Havoline is a product of ChevronTexaco Corp. Combined with the changes in the formulation due to changes in the API Service category, the only thing that stayed the same was the name. Ken

But I just pulled the valve cover last week to adjust/check the valve lash and it is clean. This motor should go another 168000 miles. I am sure the newer Pennzoil is great stuff, and I would even consider using it again. But I have other choices, and I am sure I am not the only one to have this happen.
quote:I don't mean to clog up the thread, but... Linux has several great GUI's. Well, to be more correct, environments. I'm a die hard Gnome person myself. If I was rolling in the dough, I'd buy myself a Mac, because really, it looks like they've taken Unix to a whole new level in easy to use effciency, but I'm quite happy with my Mandrake setup for now. I got to tinker with OS/2 for a little bit, well after it had been abandoned, though. Quite interesting nad surprising that Win95 took over.
guitargeek, Linux, Mac OS 10, and graphical interfaces for Unix look a whole lot more exciting to me then what Microsoft has to offer. Unix in many ways is probably the best computer operating system-all it needs is a great graphical user interface. And actually, in something like 1993 or 1994, IBM (Big Blue) came out with perhaps the greatest operating system of all time-O/S2. It could have been improved. The world adopted Windows 95.
