What Engine Oil To Use?
Gday All,
Now that I dont have an overheating engine, I am getting the buggy ready for racing again.
The next race will be 700km long, non-stop (except refuel) with an average speed of 120km/h, and my engine running over 6000rpm for 90% of the race.
What oil viscosity do people suggest?
Obviously I will use full synthetic, but should I use a straight or variable grade, if so, what grade?
Ambient temp should be about 25 deg celsius, engine temp should be around 85 deg c, and engine is in stock form.
I am a bit worried the engine might not stay together under these conditions, and would like to gear-up for less rpm, but that will sacrifice acceleration, which I am already 40-50 whp down on the nissans and toyota engines....so I guess I will just hope for the best!!!
Thanks, Steve
