karmavore Posted September 1, 2005 Report Share Posted September 1, 2005 I notice Dermot is running RP. I have a friend that uses it in his car too and likes it a lot. I'm thinking about a switch in part cos Mobil 1 is getting nearly as expensive. What viscosity though?? When I first got my S4 I was using 10W-30 (I didn't know this was way off cos the PO's DEALER was running it) and when real hot at idle the oil pressure light would go on. I very quickly switched to M1 15W-50 and have had no pressure problems since. Problem is, RP doesn Quote Luke Colorado, Super Spy. - Lotus Owner No Longer 1987 Zender Widebody 560SEC | 1994 Lotus Esprit S4 | 2013 Honda Fit EV (#269) Link to comment Share on other sites More sharing options...

Htown Posted September 1, 2005 Report Share Posted September 1, 2005 Yes, but my car sees VERY little street use... Quote "Firearms stand next in importance to the Constitution itself.

Htown Posted September 1, 2005 Report Share Posted September 1, 2005 On the street, maybe 35-40miles a month...I live real close to work, and the track, and usually drive my Audi S4. On the track, maybe ~100-150miles a month aprox 6-8 months of the year. Quote "Firearms stand next in importance to the Constitution itself.

karmavore Posted September 2, 2005 Author Report Share Posted September 2, 2005 Do you think 20W-50 won't be viscous enough on the cold side?

Dermot Posted September 2, 2005 Report Share Posted September 2, 2005 Luke, I am told that RP has excellent bearing protection properties. I have the Racing 41 in the car at the minute. It is too thin and I am using a bit of oil. RP do not publish the data on their oils but I got out of them that Racing 41 does not meet the Lotus minimim vicosity test at 100 deg C. I will change to Racing 51 in a few weeks. Dermot Quote Lotusesprit.org Link to comment Share on other sites More sharing options...
karmavore Posted September 2, 2005 Author Report Share Posted September 2, 2005 Isn't racing oil a bad idea in a street car?

karmavore Posted September 3, 2005 Author Report Share Posted September 3, 2005 Just picked up a case of RP 20W-50. Will try in a few weeks. It's actually cheaper than M1. The RP cost me ~$56. A case of M1 would cost ~$62.
