Oil for a V8

(1/2) > >>

bonio73:
I just bought a 110 V8 (1990).  Can anyone tell me (due to lack of any form of manual, Haynes or otherwise) what type of engine oil I should be putting in it?

Cheers

jjsaul:
all standard rover v8's in LR/RRC etc should be fed 20W50  :lol:

as for what type its up to you, but i have always used mineral oil rather than synthetic or semi synthetic.

beast5680:
mine runs on 15w40 no probs :D

My old one used to drink a bit and I found using Lucas 20/w50 with their stabiliser cut that out.  15/w40 is within the spec for later V8s but the engine is old school whenit comes to oil, thick and slow to fill in the gaps.

I think this is the one I use.  Ã‚£26 for 9 1/2 litres

Eeyore:
I'd use a good quality, semi-synthetic 20/50w (we use a Millers SOR in the racer, but that may be a bit overkill). There's a good reason for this. The cam system wears and when it starts to wear you can get oil foaming on the hydraulic lifters (known as 'pump-up') which induces an intermitant misfire which is a total cow to trace. Better quality oils don't foam as much and very much limit the hydraulic pump-up problem.

I kid you not - if you've a mystery misfire on a v8, try changing the oil as well as the coil etc! Top tip of the day!
