Mazda Skyactiv has an air/oil separator. (before the PCV valve) Still if there is a market you can be sold a can. (money before brains)

We all would chip in a quarter for gas and hop in Rusty’s 67 Camaro and go down to Huntington Beach. Our bathing suits were shorts cut from blue jeans, normal for that day.

If you just focus on the oil side of it then your whipping boy is CAFE regulations and your super powers to bearing wear is HT/HS higher viscosity. The bigger picture is the fuel blend in the world region used, and all the hardware in the modern engine designed to work for the oil. I can even...

Balance is really the key.

Thanks for the info… Not a “regular” here….

Interesting test of old oil.

I did pick PUP due to the Borate Ester additive. https://bobistheoilguy.com/forums/threads/unveiling-the-superiority-of-pennzoil-ultra-platinum-oil-a-detailed-analysis-by-mr-lake-speed-jr.370226/

Moly is an element, it is bonded to sulphur in different amounts to form a molecule. It works as intended when the oil gets hot. Boron also is not the straight boron atom just a form that works in oil and works in cold start oil. Not that I know a whole lot about it but they are not a moly or...

Looks like my 2019 Miata. The Skyactiv is kinda picky on the oil filter due to the dual PSI oil pump. Mazda OEM oil filter recommended, but one aftermarket filter is made to cater to the Skyactiv engine. I started with a high moly oil but setteled with Pennzoil Ultra Platinum. Personally go with...

Here is a post from 2009. https://bobistheoilguy.com/forums/threads/how-long-has-5w20-been-around.115391/ 5w20 was originally not synthetic.

Kinda like engine technology is hardware and oil is software. Like the info that USA/Canada does not control the world view with its CAFE regulations. Get used to thin, here to stay. (for some engines) 5w20 has been around for some engines for a really long time and seems to work fine.

But proof is how long they last at the recommended viscosity. Somehow they will always say they know better than another. The majority follow the recommendations. Even the military has reduced viscosity with little regard to CAFE laws and had not taken a hit on reliability. New engines are...

Mobil 1 formulations have changed, not saying better or worse. TGMO has a strong additive package with a lot of dinuclear moly but I quit using it when found the base oil inferior to GTL base. Now use Pennzoil Ultra Platinum with a strong additive package and GTL. Definately wait for the rebate...

Thank you.

Just thinking from my view. The turbo increases the load on the main bearings. Maybe secondary the oil temperature at the turbo bearings.
