In Reply to: oil consumption - 1990 3251 posted by JJ on June 03, 2000 at 23:44:31:
: Would like input on oil consumption. My 1990 325i has 93k mi. First 1500 mi after oil change w/ 10/40 Valvoline - no consumption. In ten days thereafter down a quart. Same thing happened last oil change, both times after oil level sensor came on. Does a slight reduction in level result in greater consumption? Does running at higher RPMs (4000-4500) have a meaningful effect? I show no signs of leakage or unusual exhaust smoke. Thanks.
Thinner oils will disappear faster. Try
switching to Castrol 20w-50 GTX, i've found it
to yeild higher oil pressures and lower oil
temperatures than all the other name-brand
dino oils. And yes higher RPM will use oil
faster. It's not uncommon to have to add a
quart every thousand miles on a 325i/is.
