My friend following me the other day said that I have the odd plume of blue when kickdown is used, but the car doesn't seem to use a lot of oil.

It uses perhaps just under a pint every 1000 miles.

What oil would be best to use in my 165k mile 300SE on LPG?

Currently on a fresh filling on 10W40

Cheers

oily!

hi, the oils ok, its probably just valve stem seals gone hard, common on these, they can be changed in situ, good indie would know. shouldnt be to dear if your bothered or dont kick down to often , at that mileage it may be one kick to many for the old girl! 15 years with new 190E and E210 and never used kick down once , have pulled it down to 3 or 4 on the stick but only when climbing hills etc, wouldnt bother with expensive oil its as its getting oil changed on regular basis! all the best .

About the only good thing that LPG offers other than its current price is that it has almost no detrimental effect on the lubricating oil, just use a half decent one and get those stem seals sorted, at least the inlet valve ones.

I've done stem seals before... Albeit on my Morris Minor.
The rocker cover gasket needs doing anyway as it's leaking past the seal, two birds with one stone!

Cheers chaps
