this is what ive wanted to put in for a while but not sure if its a good idea as the motor has always been ran on 10 40 semi syn and is not far off the 100K mark. that wouldnt bother me but i know semi syn isn't up to the job of track days which is why i want to start using fully syn. what do you guys think?

no problem at all. being a fully synth, will retain its viscosity a bit better at the high temp so good for an engine with a few k's on it and especially if you're going to be tracking it then you want a fully syn. the 5W means it'll circulate round your engine quicker upon start-up giving more protection when cold. If you're worried about compatibility of going from a part syn to a fully, or from a 10W-40 to a 5W-40, that's not an issue

no worries cheers for the reply.
all i was concerned about was going from a semi syn to fully syn as the motor has a few K's on the clock and have heard a few people say its not such a good idea on an old engine. think ill give it a go and see how she does as like you say semi syn isn't designed for track use.

that's carried over from scare stories on *really* old engines where new synthetic oils would dislodge deposits, which would either cause leaks or block oilways. doesn't really apply to anything built in the last 30 years tho

Norton Way Honda seems to have switched back to 10/40 semi-synth, so they're all running on that now.

They were (IIRC) using that (Magnatec) back in the early noughties, when the cars were new. When they switched to SLX 0/30 synth, it was like bloody water & just leaked out.

So far, only the S2000's ever thrown a rod, but we never actually discovered the cause, other than some do that sometimes.

I always stock up on it when halfords have it on half price, plus I use my trade discount card on the offer too, £16 for 4 litres
