help! i can smell petrol in my oil

[snoops]

when i checked my oil it doesnt smell like oil it smells strongly of petrol?

[johnono]

if youroil is old / black it will have residues from combustion, as it is afterall used to lubricate insige the bores

if you notice blue smoke on ignition then i would consider having the head off and changing the piston rings

change the oil sharpish.... car run ok?any difference with cold weather?

[snoops]

it is quite black and i also have an oil leak i think cos there is a puddle of oil under my car but the oil doesnt seem to be going down? can any1 help?

[snoops]

the car runs fine it smokes quite a bit cant really say any change in cold weather but it chugs a bit and cuts out sometimes

[gcorky]

when was it changed last??

[snoops]

which oil wouldyou recommend for 1988 325i 136k

[snoops]

dont know when it was changed as i bought it a couple of days ago

Fully service it mate - oil wise, i use Magatec 10 / 50 though this can cause some old engines to run quite tappy, if this is the case drain it again and use 20 / 50

Smoke could also be down to the valve seals in the head being in need of changing because of wear - if your gonna do this, you'd be best off buying a complete head set from BMW and doing everything invovled for piece of mind.

Petrol in oil is 'a very very bad thing' for your engine. Change the oil.
You may want to do a compression check to verify that your rings are intact.
