I have been turbo since November, the oil was changed 300 miles or so before the install. So, I have about 1000 miles or so before the 3000 mile mark. I have in there now conventional 5w-30 (Valvoline). The JDM DE I have has between 80 and 100k on it by now.
I had planned to stay with the conventional oil and change the oil not a mile above 3000. I had also planned on doing some roadcoarse laps in the future, when a new track that is being built near me gets finished. I propose to change my oil out to a Valvoline racing conventional oil right before I go to the track, then change it back to the 5w-30 when I go home. There was a time when I had considered using a synthetic blend, since it is not much more in price than conventional. But what are the benefits of the blend vs. conventional? How many of the benefits of full synthetic are shared with the blend? I would like to know these things.
Im hesitant to go to full synthetic because I am afraid that it will clean up too much around the seals and start oil leaks. From what I understand, oil is oil, and the real advantage of full synthetic is longer change intervals. Also, my team leader at work, who races, told me that he switched from Amsoil in his race car to conventional because the synthetic was thinner and caused temps. to go up. He advised me to stay with the conventional.
Does this plan sound good? Or should I just go with the synthetic blend/full synthetic? In the meantime, I am going to do another Blackstone analysis. I cant remember whether or not they advise on which type of oil to use. The last time I had one done when I was NA, I had some minor gas contamination, that was the only issue. Honestly right now, I am smelling gas in the oil when I check the dipstick. But that is another thread I suppose.
