Hello.!
I planning to put Valvoline Racing 20W-50 oil to my car 2,0 8V,does anybody have any experience about that.I think it's good for the summer but not winter...?

Regards,Mikko

20w50 may be too thick,you cant go far wrong with a quality grade like 10w40 magnatec.(castrol)

Yes - I think 10W40 is the recommended viscosity for all petrol-engined UK based 155s.

20W50 is a touch thicker but as you say, it shouldn't be a problem in the summer. I'd put 10W40 in it again for winter.

I use Selenia 20K (nee "Formula Alfa Romeo) - it's a semi-synthetic 10W40. My old 33 P4 ran on it from day one (apart from a brief affair with Shell Helix when I couldn't find some once) and the motor didn't burn any oil, even with 80,000 miles up, so I'm guessing the engine wear was almosy non-existent.

Hello !
I use 0W40 Castrol fully synthetic Racing Oil for over 2 years, all is running fine !
the engine needs a little bit of refill during the service, but not too much !
I think 20W40 is a little bit to thick !
greetings !
