Oil consumption through the roof since oil change
Discussion
Hi All,
Recently changed the oil on my wife's 120i (2005 90,000 miles, N46 engine) from the unknown oil it had when we bought it to Fuchs Titan fully synthetic as recommended by Opie Oils.
before the change it needed a litre top up every 1500-2000 miles which i think was reasonable. the CCv system has been replaced also and MOT emissions are fine.
since the change it is going through a litre every 300-500 miles which is massively excessive and has blue smoke coming out of the exhaust under load
i think that the new oil is too thin and getting past some probably well worn rings and seals
my question is, can i go slightly thicker on the oil to prevent this? its slightly frustrating as the oil was £60 and i think we've burnt most of it

Before changing the oil to something less viscous, I would see if you can find out what oil is in there just now and confirm against your manufacturer's manual that it meets the required specs.Recently changed the oil on my wife's 120i (2005 90,000 miles, N46 engine) from the unknown oil it had when we bought it to Fuchs Titan fully synthetic as recommended by Opie Oils.

Also might be worth confirming you don't have a subtle leak somewhere, such as from the oil filter or sump plug.
The blue smoke definitely seems like it's burning oil, but also might have been an ongoing problem that you've perhaps not noticed until this oil change.
If you've burnt most of the oil and haven't replaced it, make sure you've not driving the car without enough oil in it.

no oil leaks at all anywhere on the car, its definitely coming out of the exhaust were topping up as we go (just put another litre in today) Also might be worth confirming you don't have a subtle leak somewhere, such as from the oil filter or sump plug.

car is probably a bit tired at this age and mileage but not happened at all until this new oil went in

Maybe the previous owner filled it with 20w50 or something?
i hope not, the receipt from the garage says castrol 5w-30 and weve probably topped up 4 litres this year with mobil1 1 5w-30 as its slowly used oil (does about 13,000 miles a year) so even if it had been bodged there wouldnt be much of that oil left in the engine anyway Gassing Station | Home Mechanics | Top of Page | What's New | My Stuff
