First off, I'm in ohio. I used to run Joe Gibbs XP4 (15-50) but the shop who put on my
oil thermostat talked me into royal purple, I think 5-15. I was concerned about how thick (maple syrup) with cold start up, etc. But the "sticking" qualities have got me thinking again. I wish we all could come to a consensus. What do you all think. 427 windsor, 550HP/550TQ.
Accusump: I have been thinking about installing one of these systems on my car as well. How many different components need to be ordered? I notice they don't have a kit. I'd like to get it put on over the winter.
