Title: OIL for 8V GTI/ Valve Stem
Post by: StephenEggo on 20 February 2007, 21:23: Hi guys just wondered what oil to put into my 1991 8v gti. Its done 140,000 now and is currently running on duckhams 10-40 semi sythetic.

The engine does use oil around 1 litre to every 1.5-2k miles. I think the valve stem oil seals are maybe showing signs of wear.

Anyway the car is being serviced on thursday and I am wanting to try a different oil. I was thinkiing along the lines of castrol gtx magnatex 15-40. I heard the vw stuff is pretty good as well but I was thinking that 10-40 maybe a little thin if the car is using oil.

I have also just started to notice shades of blue smoke emitting from the exhaust when the engine is reved when cold. Could this be serious?

Cheers

Does sound as though the oil seals may be on the way- not a huge job but worth doing.

No, i tried it, no difference. The 40 is the viscosity anyways so you would need a 10/50 or 15/50 if you wanted to try a thicker oil.
