RE: Warming up the Engine

[Aleksander Mierzwa <alex@matrix.com.pl>]

I usually idle the engine only for about 1 minute after startup (just
enough to close the garage door) to let the oil reach the camshaft area.
The engine warms up faster while driving and you have better oil
pressure.
Putting synthetic oil into an old engine that has been run on dino juice
before may (but doesn't have to) cause leaks. Other concern is that the
0W30 is so thin it can cause low oil pressure. I never had any problems
running Elf 5W40, though.
