as above, what oil should i use in my cossie? its got a 4,000 mile engine in it (so not too much wear and tear)...... the oil i'm using makes the engine sound like a tractor after a 20 mins of flat out driving....leave it running to cool down etc and it goes quiet again.. any suggestions? cheers tony

 

Hi Tone, I use Silkolene Pro S 10W-50. Should be okay for the odd trackday too, but if in doubt the Oilman ( http://www.opieoils.co.uk/ ) can advise...

What have you got in it at the minute?

Hope you're well

 

hi bill i'm cool ta... long time no hear.. i hope things are ok your end? i got magnatec in it at the moment... ok for normal road use but not up to track tempratures... cheers mate

 

pro s just be advised by oil man, so i bought 2

for the cossie i "think" you need pro r

 

Castrol is famous for losing it's viscosity like this.
Use Silkolene pro s, and fitr a stat oil cooler if doing track days again, as oil is obviously roasting, remember the oil is always around 30/40C hotter than the water and does as much cooling.

as above, had good results with pro s

just did on oil change on the scooby and have used it to. quiet as a church mouse now
