I too, have a small contribution to this. I agree with Scott that,
particularlyin a highly tuned engine Mobil 1 is the stuff. I have used it in
the Dutton
since its current engine was run-in(3 years) and when you look down the filler
cap, the rockers etc look clean and shiney; not bad on a UK Ford.
Another experience confirmed this view. I was driving along a dual-carriageway
at about 85 when something struck the underside of the car. Two miles further
on I met a large stationary queue of traffic, whereupon a large cloud of steam
emmanated from under the car. On investigation: two bolts bashed off the water
pump and NO water! A replacement pump was fitted and: NO nasty noises, no
compression lost, no problem! I attribute this luck to the use of Mobil 1
and competition bearings.
