Oil (again)

[Jonesey]

Is it ok to use Castrol 10w30 fully synthetic in a firestorm?

[Jazzscot]

I thought that using fully synthetic oil caused problems with the clutch that is why you should use semi synthetic.

That's exactly the problem.

And not that this'll be a problem with Storms, but you should never use it in a new engine either as the rings etc can't bed in properly.

[Jonesey]

So, as mine has done over 50,000 miles. should be ok then?

[tony.mon]

As long as it doesn't make your clutch slip, yes.
Try a few hard launches to see if you can cause slipping; if so switch to semi-synth.

But I'm personally not convinced it'll be better than semi, just more expensive.

Mmmm, I'm becoming a doubting thomas on this one, I think I'm going to stay with semi. Anyone want to buy 4 litres of castrol power 1 10w30? (unopened funnily enough)
