not to add fuel ( oil? ) to the fire but...

last month i switched off of the mobil 1 0w-40 to RP 10w-40. the week after the change i took a road trip and put around 3500 miles on the car in a little over a week. in total i've now put over 5k miles since the oil change. the first few days there was some smoke on start up, not a lot - more like a little puff. same as with the mobil 1, btw. since then the only time i get any smoke is when the car has sat for 3 or 4 days without being started. again small puff and then it's gone. smells like fuel not oil.

did i get any extra HP ( as RP says )? nah. seems to drive and run like it did before only a little less ticking noise when it's idling. will i use RP on the next change? no. i'm going to try something else.

the general consenus seems to be NO on mobil 1 and NO on 0w and NO on -30.

some people like castrol syntec, some people like RP, a few people stick with mobil because "that's what porsche puts in..."
