Motul 710 V's Brand X

[dc]

Or in this case, specifically Castrol Power 1 Racing.

Right guys, I think of all places, if there was a answer to this or should I say, if anyone had experienced similar with a product, it would be here. I have run 710 pretty solidly but bought some Castrol in the first instance for my Stihl equipment. I thought I would try it in the bike, we are talking X7 just now but oil is oil once in a tank. I had removed all 710.

I have just given it a small run and was a bit surprised to find the tail end, reg, cowel etc. had more oil on it than a reasonable run with Motul. I will be out again tomorrow so this might be a bit early to question it but I just wondered if any of you had found similar with this product. It might just be an accumulation after ticking over a bit but I have never seen that much before. Or, is it that 710 burns so well?

I know I can check the pump setting but it seems far too coincidental when I have switched oil. In fact, as I write this, I am almost certainly going back to 710 but will give it the benefit of the doubt tomorrow, weather permitting.

I suppose I could ease the feed back a little but I have it set slightly, and I mean slightly on the weaker side anyway on the basis today's oils are far better than those in the 80's and there's certainly enough lubrication, plus I don't want to weaken it just to stop this when 710 works as it stands with no issues.

Personally I would never decrease the amount of oil going through the motor.
2 strokes don't last as long as 4 strokes because of the lubrication method, so less is never good news.
Motul 710 is widely acknowledged to be one of the best oils money can buy.
It seems to me that some of these modern oils don't burn away the same as the older oils, they just appear to pass through without making much carbon at all, or fouling the plugs. Just an observation of mine, may be wrong.

If that's an observation is yours, then I am inclined to go along with it. I won't be reducing the oil. I think your reply has simply compounded my thoughts.

In fact, I don't know if you have noticed but the Motul is a far thicker oil than the Castrol which is very slippery so there is some significant difference to start with.

Must be riding too slow if its covering the tail end. Get some Rock Oil.

There are differences in Viscosity within the same spec. The specs, dictate amongst other things that the oil is compatible for use with a pumped system.

I wonder if the Castrol has a higher VI than the Motul? With it being thinner during these colder months, one could say it may allow easier passage through the pump. Maybe that's behind the issue but I have not seen it ever with Motul, summer or winter. Microns are fitted so they will throw it up more than standard exhausts, it might be a good thing with better lubrication. Anyway, I will give it another try and report back.

i have always used Castrol Power1 Racing 2T and it's been fine. No masses of oil.
I will add though that the 710 does smell lovely

[pedheadfred]

I've always used Castrol power 1 racing spec n my Jawa gprs70 race bike and it revs to over 16000rpm with no problems with lubrication.
I've been looking at oil on eBay for the Rs125 and Rz250rr, exol Optima fully synthetic 2 stroke £24:99 for 5ltrs.
Or there's another Westway fully synthetic racing 2 stroke £39:99 for 10ltrs anybody used the Westway stuff

[headcoats]

Westway is local to me and he sells Exol Optima too
I use Exol stuff but i reckon Westway is probably same stuff !

I am pretty sure if it hadn't been for the Motul, I doubt I would have mentioned it treating it as normal. A few said the Castrol smelled nice as well, I will see about that later but Motul is nice.

A spoon of Castrol R in the tank, they used to say 😉

I’ve been using the Westway oil for a number of years now after getting a recommendation from this forum. Not had any issues and the bike gets plenty of use but I rarely thrash my 4lo now.

Well there is a reason i only sell 510 and 710 oil personalty i use the 510 in most of my bikes with auto lube i have found its fine. On fast tuned motors i use the 710 same for pri mix 710 . its low ash so doesnt smoke as much and oil up plugs and clean plugs means better performance in the long run .

Clearly there is. Having had a 6 mile run today, the bike looked like it would had done a longer run with Motul.
I did check the pump setting just in case it had changed, it was right on the mark and the carbs are set perfect.
It ran and ticked over unaided perfectly but it does that anyway.



I can say, I think Castrol produces a little less smoke when you open it up and clear the pipes BUT, it does not have the nice smell of Motul. Non two strike lovers will disagree 😉.

I guess the upswept Microns don't help as they pop it out and it likely sticks on in the drag.

Been using westway for a couple of years now and it seems no different to more expensive known brands ! Think all modern sythetic oils are good. Just couldn't justify paying 13-15 quid a litre ! what's in it gold ??must be some mark up on this stuff?

[arrow]

I think the 710 is about £17 a litre.

[dc]

Best bought in 4L can.


Edit

I see it is also in Norbo's shop @ £13.50 per Litre. That's a pretty good price if it is up to date, there will be postage but if if buying a couple or adding to order it should be fine. 

[pedheadfred]

I spoke to somebody at Westway oils today about there racing 2 stroke oil as the Exol Optima racing 2 Stroke has Westway on the label now.
My question was straight forward what's the best oil for a 2 stroke they sell ?
His answers suprised me he said buy the Exol oil as it has a proven track record in racing.
So I've purchased 5ltrs £23:95 delivered fully synthetic racing 2T oil

[dc]

Just to update this. The Castrol was removed today and Motul put back. Back to normal. Minimal evidence of oil around the exhaust outlets and nothing around the rest worth mentioning. On a longer run with mixed riding there will be and that's to be expected but not the mess after a short trip.

I mentioned above in my edited post, Norbo has it in his shop but in case anyone missed that, it's £13.50 and if the price is correct, that's pretty decent. Added to to an order or even buying a couple, I would imagine it works out fine.
Since I am RD'less as yet, it's unlikely I will add to an order plus I have a good amount left, 4L lasts a while 😊.

I only bought the Castrol because it's pink and it allows any foreign objects in Stihl fuel tanks to show up. Bits of hedge that may have got in etc.

iv actually went the other way, from Motul to the castrol because i couldnt find motul that day, im on my second tank of it now and i find it smokes less than the motul and seems to clear its throat better after tootling about around towns.
