Engine oil Mobil or Castrol

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.

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.

Mobil 1 full synthetic and Mobil 1 filter. I did cams recently on my GT and at 150k, the top end looks almost new.

any oil that meets the LL-01 standard will do, buy whatever is on sale. Castrol Edge Euro 5w30 is fine, Mobil 1 euro synthetic, whatever.

My conclusion was to use the best Castrol in the gold bottle. Of course, YOU must use the specification of weight recommended by the owners manual for the temperature range you expect to be operating in.

The gallon of Castrol is the same whether you buy it at CT or Napa.

I’ve been using Mobil1 0w-30 in it for over 20 years. My Blackstone Labs reports still come back clean with no water, fuel or antifreeze found in the oil.

I'm using Castrol GTX 20W50 because it's the only 20W50 that I can easily find locally. I tried Rotella 15W40 but I found that it gave somewhat low oil pressure on my old engine.

Mobil one didnt go well with me as i was burning oil really fast it and my engine wasn't feeling it I tend to use different brands also as i recently tried royal purple
