Mobil 1 in turbocharged vehicles will have oil temps as high as 250*, but I do understand the air-cooled engine oil for higher temps.
I drove the engine for a few hours combined and have to admit, I did go WOT. I however did not hold the RPMs long for top speed, just short runs and no extended throttle runs. I dumped the oil and was surprised how it looked, dark with some swirls. I used the remaining Mobil1 that I had in the garage.
I will go out today and get some air-cooled synthetic and start running that from now on. I also want to change the gear oil out. We don't know what grade oils are shipped in these engines so I would prefer to get good refined lubricates in it.
On a side note when I checked the engine oil first it had a heavy detergent smell to it and seemed thin.
