I guess a good question to ask Eric is; How often do you rebuild the engine?
Some might argue that an engine needs to only last until the end of the victory
lap. We must be careful to not mix purposes, apples and oranges.
And more importantly (and this will get me in trouble), we're comparing new
precision machines to MGs and Triumphs. That's like comparing Intel quad-cores
to VIC20s. Our old MG and Triumph engines, while we love them for their
simplicity, are little more than farm implement power supplies. Their
manufacturing tolerances are loose and compensated for with heavy robustness
and wearing-in. This whole thread started with a set of galled lifter faces.
That all but NEVER happens with modern engines. And its not differences in
oil. Its differences in materials and design. We have to face it. No matter
how much we love our old British hardware, its just old-school machinery.
That's what I love about it!
----------------------------------------------------------
The funny thing, in many ways, the new cars are more sensitive to certain
things than our old cars. Oil is a good example.
Audi's 1.8T engine - otherwise a very durable, tunable engine - is very
sensitive to oil weights and changes. There are
many well-documented sludge issues due to 1) Audi's very high change intervals
(up to 2003) and 2) some slight neglect
by owners. Same with a Toyota V6 engine of a few years ago (can't recall which
one, it was in early-2000's Sienna vans).
Many are also very sensitive to octane ratings.
OTOH, when I bought my Audi, I was told by the dealer that the only thing that
need breaking-in were the brakes! (Or, more
accurately, bedding in). I was told to drive the car like I planned to drive it
(other than avoiding slamming on the brakes for a
certain number of miles). And our '07 Honda Odyssey minivan didn't ask me for
it's first oil change until 5,400 miles, and the
second at 11,120 miles (it has a Maintenance Minder that tells you these
things).
On an unrelated note (and similarly off-topic!) I have the pleasure of
announcing a new driver in our household. My youngest
son passed his test on Monday. So now I am REALLY going to have to get my '76 B
on the road again, just so I have
something to drive this spring! Oh, hey, that was MG content!
