Holy crap dude that's awesome! Tell me your secrets.
Although I think I've stumbled apon your answers to these before. What premix and oil?

 

Thank you. It's first 120,000 miles were all highway miles. Lately, my daily drives have only been in the city. I would drive it on the freeway -wide open throttle- at least once a week on my way home from work. I've never tracked the car but have grip-driven it in the winding roads of Mulholland Drive. I haven't changed the rate of OMP injection, started using Valvoline 5W30 and premix with Pennzoil 10-15ml/gallon of TC-W3 2 cycle oil when the car passed 139,000 miles last November. I looked through the receipts the original owner provided and I don't see any records of re-flashes done

Everything in the car are still its original 2004 parts. Besides those that require routine maintenance; the previous owner replaced the right engine mount, and Cat-Converter. I've only fixed the sun visors, replaced the radiator, the clutch bracket, clutch, pressure plate, and the throw-out bearing of the car. I haven't used any engine cleaner to decarbonize it, neither have the previous owner. No records of accident, I'm the second owner and I've had the car since June of 2009.

 

Thanks for the bump. I haven't even had this thread and the survey come to mind at all for over a month. I'll get to work on the data.

94 responses.

 

Here is a link to the data as it sits now if anyone wants to look at it or copy it off for their own spinning.

Only 2 columns deleted, 8club ID and email address. There are some confusing responses in there, as well as some clean up with Miles vs KM to get everything standardized.

Just eyeballed the spreadsheet and it looks like about 5% required a new engine. Had I known this before buying my 2009, I would have probably saved some and gone for a 2005. The horror stories relating to S1 engines put me off going for a pre-2009 car.

 

Just found this and its very interesting. Not nearly as many failures as I thought based upon just reading threads. Great work - Thanks!

 

I have all the data still, but never got enough responses for it to be more than "interesting". (Several people predicted this result )

Yours was the 104th response.
