Jleclainche Posted August 12, 2004 Share Posted August 12, 2004 Oilman, Following the long thread on oil, and your obviously extensive knowledge of the matter... I am presently using Castrol GTX 20W50 in my Lotus Seven S4 Twin Cam. This is a very recently rebuilt engine (less than 1000 miles), with 10:1 CR, 152 hp (flywheel) at 7200 rpm, baffled wet sump, and the car is used strictly as a "fun" road car. Any suggestions for a better oil than I am using? From what I read over the past two days, maybe Mobil 1 15W50? JLC Link to comment Share on other sites More sharing options...
Sheds Moderator Posted August 12, 2004 Share Posted August 12, 2004 Jleclainche, with all due respect to you I don't think it's fair to ask Oilman to answer individual queries, especially in view of all the extremely useful information he has posted in the last couple of days. I for one have gained an enormous amount of knowledge from his and othe postings on this thread and I think all of us now have enough info to make an informed choice if we sit down and think it through. Otherwise we risk Oilman spending all his time answering questions like "The bottom end of my engine has done 10,000 miles since a rebuild and I have just done an upgrade to X bhp with throttle bodies, will this need a different oil?" For what it's worth, I think your choice of Mobil 1 15/50 for your XF is an excellent choice when you have got the running in out of the way.
