I'm using 5w40 oil ,i wouldn't go lower than 0w30 and not if you re hard tracking it (aka stay away from high temperatures to avoid low pressure)
If you find your oil never going over 105-110 Celsius because you have an oil cooler for example and never beat your car for long , there is no real reason to go thicker
It does look like the plan to go to Ecutek to refine the tune eventually. I need to get it on the road first, then have those discussions. I've already started the conversation with Bob Watanabe of Drift Office, but he's busy and I'm not ready for the wallet out talks at this time.

As for oil, thanks for the feedback. I'll start with a 5w40 and go from there. Keeps it in spec per their requirements, and gives me time to figure things out. Smelling fuel all day doesn't sound fun, that'll motivate me to move to an Ecutek arrangement sooner than later. As stated, I wanted a plug and play option and this was a good one, and I knew the tune would have to be optimized in more from all the forum threads I read.
