Last comment make sure you get it serviced on or before its due and use good oil as you are using this engine and it needs protection to give long life.
Other than more regular oil changes are there any other service items which should have their service intervals shortened? I'm thinking perhaps plugs and coil packs? I was going to plumb for colder plugs on my stage 1 but consensus seems to be its overkill for stage 1 and oem plugs are more than adequate.
