No issues I can feel when driving
I had my oil light come on about 3 weeks ago so topped up with 1 litre of Castrol Edge. Didn't think much of it as its the first time she's complained about oil since her service in December last year.
So probably can rule out the fuel in the oil, unless I need to check that again??
Not sure what plugs they are, I think whichever Audi had recommended last year, probably Bosch - service was done by Awesome GTi when they were still Revo.
Oil in the fuel, could that be the HPFP??
