Hi mate.
Im after some 25W-40 for a boat engine, its for my dad. Im just wondering what we could use as we cant find any at this grade. Any advice and info would be appreciated.

Jay.

Jay,

Your not going to find this grade, but another may well be suitable. What engine is it and what year roughly?

Cheers

Hello sikolene 5w-40 and 15w-50 are the same quality just different sae?Also what to prefer 75w80 or 75w-90 for gear oil?Are 75w-80 fully synthetic?Thank you

10w-40 or 15w-40 will be fine.

Cheers

Guy.

Yes with the Pro S and Pro R it is just a viscosity difference.

I usually recomend synthetic 75w-90.

Cheers

Guy.

Rep given, thanks.

hello!

my brother needs to change the oil, in the gearboxs, on his Suzuki Grand Vitara ( w reg) one uses 1 lt, one uses 1.5 lt, what oil do you sell, thats top notch?

He will need a GL4 74w-90, if you wanna go top notch look at synthetics such as the Silkolene Syn5 75w-90, Redline etc.

Whats the best oil for a 2001 Saxo 1.1 Desire?

Also does it need a specific anti freeze?

Cheers

10w-40 semi synthetic is fine, for anitfreeze you dont need anything special. A universal antifreeze will be fine.

Cheers

Guy.

Ive also been told the full synthetic might be better? What advantage does full have over semi if any?

Fully synthetics are better, if you want to use one go fo a 5w-40. The advantages are they protect better and last longer then the mineral based oil.

Cheers

Guy.

Thank you very much

5w-40 it is!

Plenty to choose from here http://www.opieoils.co.uk

Have a look at Fuchs and Motul for good quality/price.

what would you recomend?
thanks

5w-40 synthetic if you want the best.

10w-40 semi changed twice as often if your on a budget.

If you want the best then 5w-40 synthetic, the best of these are the ester based synthetics, they do come at cost but are worth every penny.

Have a look at Silkolene Pro S and the Motul 300v here http://www.opieoils.co.uk
