After reading, it seems Pennzoil YB is regarded as one of the best dino oils. From what I've read, it seems the formula has changed recently, shown with a lot more Boron. Is the new formula still as good as it was before?
i hope it is still the same i like that oil if it changed i will start buying Conoco Phillips products we go through a lot of oil and my wal mart will feel the pinch to some degree we buy 30-50 cases at a time when the price is rite,,although it may be better does anyone have information on it!
Problem is everyone was happy with the old formula why would they change it now? With this site alone there will be thousands of people that will stop using it if it changed for the worse of course if it got better the price might increase and everyone will start buying something else anyway..
I don't see the problem, it looks like they reduced moly and increased boron. Calcium and ZDDP look pretty much unchanged, it still has close to 2000 ppm calcium.
Chevron Delo 400 LE has been running ~500 ppm of boron for years now, and that oil is great. I personally like it more than the CI-4+ Delo.
I would also like to know the answer. I understood that Mo and ZDDP produced complex surface coatings that not only decreased wear (only slightly) but more important, decreased friction as ZDDP has a great wear protection but no so great friction reducing properties. I wonder if B does exactly the same thing as Mo.
Just know Honda factory fill is loaded with moly.Honda must know something yb does not.but i think the fact pep boys is selling yb for 9 bucks five qts plus filter something has to be adjusted.formula makes it possible to still make a small profit.did yousay oil co. making a small profit?????
