I wish I had one
Join Date: May 2008
I have owned three 33, 1st carbed, 2nd and 3rd was an Imola (I still have it).
Always used Selenia 10W40 semi synthetic. I have always been driving my cars very hard everywhere, in traffic, in the highway, in the track as I like to rev them and never had a problem with oil pressure or oil itself. Selenia looks good if you change it every 6000-7000 km. I just leave it for 5000 km as I like to be on the safe side, but you can do up to 8000-9000 as I have tried.
The consumption is not very much for the semi synth, but this will vary to everyone's engine conditions. Mine has more than 150000km on the clock and 700gr are more than enough for top ups in 5000km (I drive in a crazy city with crazy traffic, so the engine gets really hot and oil thin too).
OOO SH*T...THIS IS MY 4TH ONE
