Castrol Engine oil

I use Castrol Synthetic 10w-30 on mine.

It’s thicker oil, so I feel like it gives the engine better protection. With 272k miles on it, I figured why not.

Pros: better engine protection
Cons: thicker oil
Mileage: 437734 km

  • Exhaust smoke:

I’ve been running Castrol GTX 10w30 conventional in my 9000 Aero. Brought it to a Saab specialist and he recommended it. Need to have the valve seals redone and the oil is thick enough that it doesn’t get past the seals and no smoke. No issues running it. I change it every 3 months regardless of how far I’ve driven.

Pros: no issues running it
Cons: thick enough, no smoke
Vehicle: Saab 9000

Castrol is great option if it is not fake, also make sure to change oil every 10000km (6200 miles). Those engines are bulletproof, should cause no issues

Pros: great option
Cons: if it is not fake
Mileage: 10000 km

I'm at 308k miles and use cheap Castrol engine oil, house brand transmission fluid (the correct kind though), and the cheapest coolant I can find.

Pros: cheap engine oil
Cons: cheapest coolant
Mileage: 495677 km
