<VV> Oil change

[Padgett]

I used to have cars with very accurate oil pressure guages and my rule of 
thumb was a 2-4 psi drop at cruising speed indicated it was time to change 
the oil. Chevvies, FIATS, make did not matter and usually occurred 
somewhere between 3,000 and 5,000 miles. Was once told by someone who 
should have known that the cause was the breakdown in the long chain 
polymers that made a multi-weight oil a multi-weight.

Now that was some time ago but I still see the same thing happen.

Keep in mind that European driving may be high speed but it is also not for 
very long distances and, with few exceptions, on equivalents to our two 
lane blacktops. They have also been making tiny engines for a very long 
time and the cost of driving is much higher there than here.
