[Healeys] Oil Change Frequency

[Richard Ewald]

Well my day job is that of a service manager at a good sized card
dealership.  Call an oil change an attitude rather than a necessity would be
something that only someone that is clueless would say.  I see the results
on a daily basis of the results of no or extended oil changes and the
results of regular oil changes.
Change your oil every 7,500 miles like the factory says?  Engine runs damn
near forever with little or no problems.  Start stretching those intervals
to 10,000 miles?  PCV system will get plugged up, or the engine will get
sludged.  Both are expensive but not necessarily fatal problems.  Do 1 oil
change or less in 30,000 miles, and you will be spending your
kids inheritance on a new engine.  Also if the car is under warranty it
won't be when you cannot supply proof of the required oil changes.
Please note, I am not one of those every 3,000 miles lube it or lose it
yahoos.  I believe in following the factory recommendations for the most
part.

Comparing a lawnmower engine to a modern car engine is a bit of a fallacy to
say the least.  My daily driver probably puts more hours on the clock in 2
weeks than most people's lawnmowers do in a year.

Also Kees, you may not be aware of it, but engine oils in Europe meet a
different (and stricter) guideline than engine oils here in the US.  So
looking at oils in Europe and Oil here in the US is not exactly an apples to
apples comparison.
