The local auto supply joint has “Peak” brand oil at a reasonable price and was wonderin if any of you guys have checked it out or if it is crap. Heard rumors years ago that there is only a few refineries for auto engine oil so they are a lot of brands that are the same, different labels. True? Dunno. Thanks in advance. Fido
Well, it's probably not “crap” as it meets ( but does not say “exceeds”) API and SAE standards. Their 15w40 oil seems adequate but I wouldn't consider it a top tier product. Doesn't say what base stocks are used, nor any real indication of the quality of additive packages.
Actually, there are a lot of independent refineries that produce motor, hydraulic, and gear oils.
