Engine oil Mobil or MOTUL

I’ve been doing annual oil changes with the mobil1 15/20k oil and 15/20k filter. Oil comes out clean every year, no problems.

I've put Mobil 1 in everything I've owned for the past 30 years and change it at 10,000, but I'd never push it to 20,000.

Mobil 1 esp 5w30

$33 for a jug at AutoZone.

I used Motul 300v 15w50 for my track days at Circuit de Catalunya, Circuit de Calafat and Circuit de Castelloli because of the extreme heat.

Motul eco-lite 0w/20 bought on ebay in bulk is cheap and it’s a 100% synthetic oil (better than full synthetics). Just posted an oil analysis report from blackstone labs. It’s a very good oil.

I've been using motuls hybrid oil that's specifically for hybrid cars on my gen 3 prius. Gave me +2mpg onto of what I do and "nicer" ride

Motul testing came back and it’s pretty impressive. Definitely gives Valvoline max life a run for its money.

On my first oil change I used Mobil One Synthetic 5w30. That's what most people recommended as well, at least as far as being able to stop into a store and grab some real quick. There's probably better stuff that's pricier and harder to find.

Got some mobil 1 and it feels pretty good.

Recently got my first oil change at 5K and used mobil 1 0w40. The engine is now louder as compared to what it originally was. Not sure if it is the oil being too thin? or perhaps the cold weather.
