Problem - Performance Engine Lubes

I've had my new cc for the last 2 months now. 4 days ago i had the engine lubes changed, however instead of the original esso lubes i had it replaced with what i thought was a superior lubes, Mobil 1 (with Supersync) 5W50 Fully Synthetic. The oil filter was replaced with the original part & nothing else.

A little problem encountered on the same day. I noticed the engine temp was slightly higher than usual, i.e., above 90. i then had problem starting the car (3 attempts at the ignition) and when i checked the temp gauge again, it was getting very near to the 'red' zone. This all happened evening of the same day i had the lubes replaced. The cc is in my garage since.

Anyone any thoughts why?

could be an air lock in the oil system or is the oil the correct weight?

Shouldn't be any problems using Mobil 1 Motorsport (which is what I think the 5W50 is -- the ordinary stuff is 0W40). Has it been overfilled, or has the oil been dripped onto something it oughn't have?

Oil correct weight? viscosity yes but where do i find out about the weight?

I might have overfilled the oil slightly. but could this be a cause for the temp overrun? or perhaps performance oil prefers working at higher temp.?

Anyway, i took my car in for an immediate replacement yesterday. Got back Esso Ultron 5W40 Fully Synthetic. Drove it hard last night and temp stayed consistently below 90.
