I've been struggling with this for some time and have not yet found a decisive opinion...

I favour Mobile 1 myself in the Duratec
Have you consulted DVA ?

You could always use the same as you use in -

To be fair, it depends on the spec of the engine, and the use - thrashing or general fast road.

In our K-Series Elise we use fully syn Valvoline .
In the tuned Zetec Seven I prefer Castrol Magnatec.

I guess we need to start with a fully synthetic unless running in
Then the oil weight must be the next consideration

Running in? Is it not better to just drive it, rather then running around?

Or there is my favourite - Olive Oil

What about snake oil?

Oh that is going to start the old Racing Snake off when he logs on later

this one: http://www.opieoils.co.uk/showproduct.aspx?ProductID=68899&SEName=fuchs-titan-race-pr o-r-15w-50-ester-synthetic-engine-oil

by (some would say!) one of the best 'k' series builders in the business

Yikes that is expensive though JV

I buy Mobile1 from costco for around £27.00

I like the chilli-infused oil - goes nice with good bread....oh, wait.....

Wrong thread Hedge

I am able to get Comma Fully Synth 5w-50 Code:MS5L from my local factors

Generally Mobil 1 (10W-40). Due to having solid followers, in the past I've used the Motorsport version (15W-50) but I understand this has now been discontinued.
