Oh poo :evil:

 

What about Millers CSS 20w50? £29 or

Valvoline VR1 Racing 20w50 £19

 

No m8, save that for when it's run in.

 

These oils offer excellent protection for your engine but that isn't the idea of running an engine in.

 

If the rings/bores aren't bedded in properly it could result in a poor engine for ever more :(

 

I wouldn't pussyfoot around when running the engine in either. Don't be affraid the rev it to say 75% of its max.

 

If anyone has ever seen an engine run-in on a dyno or on the rollers they'll know what I mean. They don't potter around with it for 500 miles they rev it quite high varying the load, gradually increasing the revs.

After about an hour its at max rpm :o

 

I use £2.99 asda oil for a 200 mile run-in, changed it for valvoline and drove it to Santa Pod and run a 15.0, and the engine just gets better and better!

 

 

Just my opinions though, I sure lots of people with disagree with me :wink:

Ok ive have not got it yet as i still need axle oil to! So asda oil for running in??? :lol: really?

 

Axle oil?

Engine oil for running in?

 

Thanks

 

Yeah really :lol: , any normal 20/50 oil will do, just save the expensive stuff for when its run in. Still get some as you'll need it soon anyway.

 

I use Valvoline Racing 20/50 once run-in :wink:

 

 

Thank KJ, glad someone agrees with me :lol:
