Which Petrol and oil

will the gta's run well on regular unleaded or do they rely on a higher octane petrol (or additive). also which oil is reccomended. thank you

They run fine on unleaded no problem at all.

Oil, I use Mobil 1 15w50 version as the usual fully synthetic is too thin.

There will be others suitable, anyone?

I have always run my atmo on Shell Optimax (now V Power). Its 99 RON. The car was run on leaded before I had it 6 years ago. I also get the fuel filter changed every other year and have had no problems in this area.

As for oil, mine had run on Mobil 1 15/50 since its was three years old. I think this really should have minimised wear

My paint code is 485 (blue), BIG_MVS has two blue cars with different paint codes to mine. Which blue is 485?
