When to stop the foreplay and go full out

I don't have an oil temperature gauge in LE0, so instead I wait for the oil pressure to drop back to 2.5-3 bar at around 10 miles, which is invariably some time after operating water temperature has been reached.

 

It seems to work - only one head gasket change in 102,000 miles *biggrin*

I am glad that this isn't quite as clear cut as it could seem 😬

I must confess that I also use no 3 (wait for oil pressure to drop to 4 bar), at that time the oil is about 50 degrees.

 

How do you guys manage trackdays? The trackdays I attend is divided into 20 minute slots, so you drive for 20 minutes then have a 40 minute break, then repeat. If I where to drive miss daisy for 10 minutes+ I wouldn't get any action...so to speak *smile*

Quoting Roger Ford:

=The other reason for not goosing the car from cold is that all modern fuel injected engines run fuel enrichment from start up cold until at least 60C water temp.

Why is that a reason? Does the enrichment cause any problems? Or just waste fuel?

 

Excessive fuel can ''wash' the oil film off the bores
