Engine oil Castrol or Mannol

Castrol Edge is usually cheaper than Mobil 1 and will be as good.

Can use 5w30 or 5w40.

0w40 or 5w40 will give you slightly better engine protection if you drive at high rpms more often.

I wouldn't use anything cheaper or different than those two really. You don't need more expensive oils than those either.

Castrol edge is just fine, even the cheapest one is likely better than whatever was good 20 years ago.

I've never had any issue with standard Mannol - my cars have always had it every 5k and I'm pleased with the results.

My Skoda gets fresh mannol every 12 months. No problems so far. It meets the VAG spec so all fine in my opinion.

Michigan I use 0w20 Castrol Edge all year.

As long as you're not getting cheap gas station brand oil, you'll be fine. I've been using Castrol Edge 5w40.

Mate, just get Castrol Magnatec 5w30 full synthetic and change it every 8000km or 1 year, don't fall for snake oil propoganda

Al producătorului, Mobil1 sau Ravenol în general. E ok și Castrol doar că în experiența mea se înnegrește mai repede și trebuie schimbat mai repede pentru o funcționare lină a motorului.

One time I had the oil bug bite (keera) and I decided to get the best oil. Castrol (I don't remember the number) but it was 340 AED for a gallon. I poured it into the engine and it felt good. That weekend took it for a desert drive and during one of the breaks, the entire oil just leaked out of the main seal. The oil was so good that the engine didn't have the tolerances to hold it back.
