Oil temperature during normal use
Discussion
Greg,
Thank you for your reply.
My car runs on 00W40 oil, which is very low density.
The engine is in absolutely superb condition; an overall fuel consumption of 28-29 mpg (no matter how fast the car is driven!) shows the original owner had run it in extremely carefully (usually I am granted with comments such as : "are you still running it in?!", "is it new?", etc.
)
Therefore, my question takes account of a car which is in as-new condition (engine wise); actually I am used to covering something like 10-15 miles before revving above 3000rpm.
The oil is now 12,000 miles old, and I should be replacing it in the following weeks.
Anyway I haven't taken the wheel since January.I happen to go to the garage at least twice a month just to start it (bl**dy heavy studies= no time for anything
)

Obviously don't rev it above 3-4k revs until coolant warm, then drive gently for a few more miles after that.
Yep mate, that was taken for granted when the car was bought

making sure the oil is always above min
No worries about that!

and changed at least every 6k miles.
Whoops!

There can also be a danger of choosing oils that are far too thin for the application, say 0W30, as these have poor heat characteristics when the engine is warm and can be too thin for certain applications (like Turbo bearings). Sometimes, they can be so thin that you'll get blue smoke from the exhaust at high revs.
The service book shows it has always been under Mobil 1 00W40
What actualy worries me is the white smoke from the exhaust when I start it up...but (luckily ?) disapppears after a while.

Thank you Domster, and Greg for the smoke thing;
about changing the oil, I just intend to respect what's written in the owner's manual: change every 12,000 miles.
Do you think that's reasonably often on a ten year old car?
(if matters: current oil consumption= 1 L / 1,200 miles)

but Mobil 1 in a 'clean' engine like the S2's (my oil was always honey coloured!)
Like mine now.

Leaving it to 12k may not do much damage
Phew!

This is easy enough to do yourself for about 50 quid, or get a local garage to do it - doesn't need to appear on service book as not an official interval, but next owners (and you!) will eventually appreciate it.
Yes I know this, I'm not completely 'new' in the business...
Anyway thank you for your help!
