apart from a letter "S" that seems to cost 10 quid

can anyone actually tell me the difference between these two, i bought the GPS today

i'm all for high quality motorcycle oil, and the best protection for my engine blahdy blah, but the difference between 15 quid and 25 quid is fairly serious for 4 litres of liquid, that gets binned (taken to the dump officer) every 3000 miles

is GPS necessary over GP, unless i want to ride in the Arctic Circle?
bike is CBR400 NC29

curiously yours

Goosey, I think the S is for synthetic.... don't stress over it. Save your £10 and have a pint instead Thumbs Up

Maybe it includes free re-fills. Laughing

so long as the oil is decent and to a sufficient level then it will be fine.

£10 a pint is steep, £5 will buy you a pint of leffe, perhaps put a quadruple vodka into it?

I personally hate fully synthetic oil so its certianly not worth £10 extra, but considering its going in a high performance inline 4 then it may be worth the difference to you.

I personally use Putoline Semi-Synthectic Oil Smile

I use castrol GTX which is another £5 cheaper for a litre more and change it regularly. Here is why I can get away with it.

Yo, Goosey. Fully synthetic oil has a high chance of causing clutch-slip on your bike...

I put in castrol, 10w40 part synthetic GPS. Does the trick... Same oils as you bought i think.

Part synthetic is not fully Synthetic, so its fine.
Dont bother with base mineral oil (ie GP); a bit crap. The 400 revs pretty high.

Got it?; 10w40 Part synthetic... Any decent brand, and you will be ok.

I know the Castrol 10w40 Part syn. GPS is expensive, but it's a specialised engine...worth it!

i know this will get flamed, but Middle Finger

i am using oil i took out of the cbr every 3k mile in my klr's. i ant spending £25 on more oil and my engines 20 year old anyway so oil then must have been worse Question

And most of it leaks out anyway Evil or Very Mad

Yer but the oil you're using will have 3k miles worth of engine "wear" and "degradation".

Cant afford a tenner for some nice new, mineral oil? Probably be alot better using new base mineral than old part synthetic...

Sup to you though m8. I suppose, If it leaks then there is not muh point in shelling out. My car does that, and i put cheapo crap in... I dont like my car, and it doesn't like me...

cheers peeps

and yeh i took a bottle of R4 to the tills by mistake, plus a tyre pressure guage (fiver) and the total was just shy of 40 quid!

When I put fully synth in my bike it made it faster ! Twisted Evil

I'll be using fully synth from now on then! Very Happy

I doubt it would make a difference ona 400 though...

Yer,it's not worth the money or the risk of clutch-slip with the R4 TBH...

The oil you've got is very good!

WildGoose · White Van Man Joined: 21 Mar 2002 Karma :

yeh ive heard about the clutch slip issue, i used to put R4 in the R6 and stuff, but never did in my cbr250

speaking of which, anyone need a litre of R4? i have one spare

GPS is the castrol 'premium' semi-synth.

Castrol r4 is the 'premium' fully-synth, at about £30 for four litres.

A better fuel, especially something like the r4, should work better in high-rpm engines and provide less resistance, though may need to be changed more quickly. Some of the stupidly expensive oils claim to give a 5% increase in power or something.

Note that most sports bikes apparantly should be fine with fully synth, but it seems some aftermarket clutch plates (ebc) don't work so well with it.

In big sports bikes I go for GPS/r4. For stuff like the dr I stick any old cheap stuff in Smile

.
For the CBR? Well, what do you want it for? If you're going to be treating it 'nicely' I'd get the dip in power looked at so it's actually running right. Doesn't seem much point keeping your engine expensively lubricated when something's not working as it should in the first place.

Stinkywheel: I suspect the '1984 Honda V65 Sabre' that they are testing doesn't rev quite as high as goose's cbr400 or my 15,200rpm red line on the r6 Smile

I tried R4 once and the bike didn't like it, would run like bollocks until properly warmed up so went back to using good ol' dependable semi-synth GPS. All the oil that comes out of the R1 I save for the car anyway 'cos it goes through it at an alarming rate Razz

Oil's oil in my eyes, plus it only stays in my bike for 2000 Miles.

But I won't use crap!
