98 Mirage

[ItsBoostin]

Girlfiends little mirage is using heaps of oil? normally holds around 3.3ltrs but the last 2 services ive done on it ive only taken out about 1.5ltrs?? A coulpe of times ive had to give it a massive top up because the engine light has come on. Took the plugs out on the weekend and they where all fouled with burnt oil and gunk.

i service it every 5000km started with 10w-40 oil but moved up to 15w-40 becuase of the oil loss.

Car has done around 170000kms

Any ideas on why this keeps happerning any help would be great

Thanks.

does the car blow any smoke?

[ItsBoostin]

No doesnt blow any smoke smell oily or leave any oil stains anywhere.

engine bay is fairly clean too.

cmon give the por old thing a break. 10w40 would be ok for its first 50000klm, but its got 170 now.

even 15/40 is too thin. try some diff oil. or at least 20w50

[ItsBoostin]

Yeah thats what i thought 20w-50 and maybe up a heat range in the plugs.

I've noticed the same thing with the GF's Corolla, 10 or so years old, 140000km and burns oil like no tomorrow! pretty sure that one has 20w50 (albeit cheap shit united brand oil lol), not sure about when it had a proper service last, it blows a heap of white oily smelling smoke on cold start then is fine as far as I can tell. Surely plugs wouldn't make that much of a dramatic difference?

[ItsBoostin]

plugs prob wouldnt make a HUGE difference just thought it could help burn away most of the gunk that was getting stuck to the old ones.

It really depends on how it was serviced in its life. Heck my corolla is now knocking on 300000 km with original engine. Just done a new water pump ( old one started leaking - Bastard to replace ) and a timing belt for good measure. Thing only uses a litre every 5000 + kms and not all of that is getting past the rings. Crank seal is leaking . Yet some pretty new cars you see these days are churning out Blue smoke when the car is less than 5 years old.

Yeah it's not something I'd expect from a Toyota, a Commodore maybe lol. Probably stupidly long service intervals are to blame though, none of their cars was properly maintained before I came on the scene argh!
