Engine oil Mobil or AMSOIL

My 911 has over 100k, I switched to 5-w40 mobil1. I’m sure driven is fine too, but mobil1 is perfect and designed for our cars, cultists be damned.

Mobil-1 FS 0W-40 is a solid choice, and you can’t go wrong with it.

Mobil 1 0w40 FS , it’s the factory fill for the car and the best choice.

Now the easiest one to find that meets my manual requirements is the Mobil 1 euro formula that’s the cool green color. The back of the bottle specifically states it meets VW specs.

If I was spending my own money I would buy Mobil 1.

I've always put Mobil1 0-W40 European car oil in my 2015 jetta since the day I bought it brand new but did notice they came out with a new 0-W30 oil but not sure if that's for the new jettas or not.

Amsoil also makes a oil specially formulated for hybrid vehicles since your engine turns on and off more frequently than an average car. Amsoil has a higher Flashpoint than most conventional oils which reduces the amount of oil your car burns.

I do all my own work and the oil changes are either 10k miles or yearly, usually yearly. I'm not too concerned about the exact date but basically every spring the cars get an oil change, air filter and cabin air filter.

Not going to lie. I use Walmart auto for my oil changes. If you synthetic premium you can pick your own oil, I use Mobil one.

I usend to run syn 15w50 in my tired old vr6 all year round, it helped with seeping issues, lifter noise and all if that. but the oil pressure would be through the roof during first start. so I'd set aside a few mins in the morning to let the car idle, relax, listen to a song and let it get some heat in it. on a normal day, the star up pressure would be .5 bar past the filter bypass (10 bar), warm idle was 2 and a bit, and everything above 3.5k was back to the bypass.
