How much difference is there between a 5w/30 and a 10w/30 syn oil .
As a fellow member of the privileged 2UZ club, I have a prediction for you: your 5k UOA will be virtually meaningless, except that it will generate some oooos and ahhhhhs of envy over in the UOA section. In a couple of weeks, I'll be pulling another sample from my wife's Sequoia. Based upon my own phenomenal results and the others I've seen here, I'm trying to decide whether there will be any reason at all to dump the oil after six months and about 4k miles (wife's local cruiser). I'm thinking of just putting on a new filter as a precaution, and going another 3-6 months then seeing where we are.quote:

Thanks to everyone for the replies. I'm going to do another change at 3000 miles, still using dino oil 10w30 and change again at 5000 miles. If I see my mpg steady out(only at 2000 now) by the 5000 mark, I will switch over to Mobil1 10w30. If its not steady yet, I will run the dino until it is steady. I dont want to switch over early, although I know you can. With Mobil1 10w30 I will stick to the 5000 mile interval and do an analysis after the first run. If all looks well I dont think I will continue analysis, but would do one again at say 25,000 miles intervals.
Great board, Ive read the messages back to page 73 already.
