Then Pennzoil comes along with their "Platinum / Ultra" (Shell) engine oils that claim 'made from natural gas'. But if they were, they would be Group IV, not III. Claim is less deposits than de-graded Mobil 1, so I'm trying that for 1st time in my gasoline engines.
TRC doesn't seem widely distributed up here. I've heard of their products, and nothing bad that I recall, but I have no direct experience.
Petro Canada's Duron line seems to have a good rep, and is noted for their wide viscosity range, 5w or 0w40 products.

Thought the main additive supplier in U.S. was Lubrizol? Or did they get bought out by a mega-corp like everybody else?
My WRX has 81,000 miles. They have a reputation for burning Mobil One, I should try Rotella T6 Synthetic one of these days. Subaru used to recommend 3,750 mi oil changes for turbos but increased it to 7,500 a few years ago. I go 5K and will use half a quart to a quart.Ex. - Subaru boxer 4s tend to beat the heck out of oil, showing up in the Shearing results. Is it a good idea to stretch OCI on one of these Sub engines.... probably not, even with most "Synthetics."

By contrast our Subaru flat six (3.0l) has an oil capacity of 7.5 quarts and uses no oil at all between changes with 171,000 miles on the odo.
I never used T6 but I'm beginning to think I should take a look at it? Up until now I've been using Deere 0W40 synthetic in 5 gallon buckets to keep the cost down. It's getting a little pricey now so I'm looking for alternatives. Sorry I'm dumb on this but is T6 pretty widely used in farm tractors? h

If it wasn't for the VERTICAL MARKETING distribution, I'd look at AMSOIL. But almost everyone who recommends it is selling it.....The best to use is AMSOIL or .

And the one thing that gets rarely discussed in all these synthetic oil discussions, is that the base stock is one thing, but the additive package of the oil can make or break any good base stock. The add pack can make up to 25% of a typical bottled oil or lube. A lousy add pack can make the best synthetic perform worse than a great petroleum base stock with a killer add pack.
Pennzoils (Shell GTL base oil is a Gr. III imported from Qatar.
GTL - Gas to Liquid
Yep. People get hung up in base stock are missing the forest for the trees. The goal of any oil is to provide lubrication, wear protection and neutralization and/or isolation of contaminants. To get those you shoot for certain performance parameters, TBN, Viscosity, NOACK, etc etc. Whether you hit those targets via base stock, additives or some combination is not really relevant as long as it hits the targets.
