Cheers

Dave

Silkolene/fuchs pro S 10W50. I got mine from here Sign up as a member (just click pug306 or something) and you'll get a discount.

DO NOT GET RIPPED OFF WITH ROYAL PURPLE LIKE I DID!

[edit]They also sell Pro R too. Same price as the Pro S

You're richer than me then. The miles I do means that I really don't want to be getting raped for £120 for oil changes twice a year.

If RP was that cheap I'd use it but lynx are selling it for £20 a litre. (although it isn't quite a litre)

That's really cheap - but it's the wrong viscosity.

You want the 20W50 Smile

Why do you use thicker oil? Wouldnt it be better to keep the oil at the right temp and use a good standard grade oil that doesnt break down?

We use a thicker oil because it offers a higher film strength.

The film strength is the most important thing, as it's what prevents metal and metal touching.

IMO, the OEM stuff (Total Quartz) isn't upto the job on the S/C'd engines. I spun a big-end when using it, and it was caused becuase there wasn't enough film strength.

I know Royal Purple is expensive, but I swear by it. I've never had an oil / lubrication related problem on all the engines i've used it in.

Also the fact it's on Touring Car Spares indicates it's use - although you can't buy it in Halfords, it's widely used in motorsport as it's superior to most other oils.

Just asked as ive had lifters tap on some motors when using thicker oil. Suppose the thicker oil will resist getting squeezed out of the bearings under the increased load. Hmm
