just a quickie.
did an oil change about 500miles back and changed the castrol bogo stuff for fully sythentic 15w 50 in my 16v.
the oil temp has gone up since. just crusin about it will creep over a 100C but at a constant 90mph for 10-15mins it was creeping just past 120C. is this too hot and could the fully synthetic cause this??
