If anyone owns a 2001 cadillac deville, please let me know if you are
having trouble with your car burning oil. I take my car in every 3000
mi. to have an oil change and the oil is alway low. Any suggestions
Number one: how low? Do you have a more specific
idea of how many miles per quart you are getting?
It's actually quite normal for these engines to consume
oil at a higher rate then a lot of the other GM engines.
This is a very high performance engine designed for
low friction operation.
There are a couple of things that you can do to
perhaps alleviate the problem. Do not overfill
the engine with oil. Because of the design of
the engine and amount of oil in the engine, if
you check the level of the oil as soon as you
shut the engine off, it will often read 1/2 to 1
quart low. If you leave the engine for 5 to
10 minutes and then check the oil, a lot
of oil drains back into the pan. Try this
for a while. Check the engine oil after the
engine has been shut off for 5-10 minutes,
and then make sure you only have it filled
to halfway between the full and add marks
on the dipstick. This engine takes 7.5 liters
of oil on an oil change, and I've installed
up to 8.5 liters after the oil pan has been
off and completely drained....so there is
a lot of oil capacity. You can easily run
the engine down a quart with no damage to
the engine. What seems to happen is that
people check the oil level as soon as the
engine is shut off, think it's low, add another
quart, now its overfull and it burns it off
due to it being overfull.
Another item, if you have the time and
a clear road where you won't get busted
by the police for stunting......drive at
about 45 miles an hour, shift down into
2nd gear, go full throttle in 2nd gear until
you get up to 70-75 miles an hour, take
your foot off the gas and let the car coast
back down to 45 (still in 2nd gear), then
repeat. Do that a couple of time a week
