I tried searching the site, but didn't quite find what I was looking for? Is Pennzoil High Mileage a conventional oil or a synthetic blend? I know they now offer a synthetic version, but I'm talking about the traditional brown bottle.
The Pennzoil site says "Pennzoil® High Mileage Vehicle® is a Pennzoil® conventional motor oil that has been enhanced with a unique combination of special conditioning agents and additives to help stop leaks from seals and reduce the oil consumption that is typical of older, worn engines. It’s a motor oil that is specifically designed for new or late model vehicles with over 75,000 miles, to help keep the engines running clean and going strong a long time, month after month and year after year."
Which sounds a lot like Valvoline's Max Life which is described as
"Valvoline MaxLife™ is specially designed to fight the four major causes of engine breakdown: leaks, deposits, friction and sludge. Through its advanced synthetic blend formulation, it supplies boosted wear protection, special seal conditioners, added detergents and anti-oxidant additives that help to maximize the life of an engine. Specially formulated to meet the needs of cars as they age past 75,000 miles, and its advanced formula can also be utilized in newer cars to help prevent the causes of engine breakdown before they ever begin"
So even though Pennzoil is conventional with added engine supplements it is still considered conventional. Is this because of the base oil it's built on? And that would mean what as far as Max Life goes? From what This Website shows, it looks like the main difference in the addpacks is, the maxlife has Sodium and the pennzoil basically doesn't, but the penzzoil has moly and boron and the maxlife pretty much doesn't. And the rest of the stuff is fairly similar and just varies in amounts.
I know these have been compared before, but what's the big difference after all is said and done?
Thanks for any reply's, I'm not trying to start a war here, just curious as usual.
