My only experience is with one 3.5 liter Rover SD1 engine, circa 1984 (pre
"stiff block"). I run it in a Lotus 7 style car (Westfield SEiGHT), mostly
for track use with a bit of in-town and highway driving. The only
lubrication changes I've made is to fit a remote oil filter, an oil cooler,
and an Accusump -- and to drill an oiling hole in the front of the valley to
help lube the timing gears (page 53, Hardcastle, "Tuning Rover V8 Engines").
I thrash it fairly hard, often for 20 minutes at a time, and oil
temperatures rise to 240F, I but try not to exceed 6,000 rpm. My only oil
issues have been oil containment -- gaskets and breathers. They are now
under control and I see no problems. The engine doesn't develop high oil
pressure -- and gets down to less than 1 bar at hot idle, but I've had no
problems and no metal or residue in the oil.
I use Valvoline 20W50 racing motor oil and change after every track day.
I hope this is useful. Good luck,
Hans
