use a full synthetic oil or not ???

[Harry hyper]

I have 2012 busa that is due for its 12k service , my dealer savage Suzuki recommend a full synthetic oil . due to these guys being so busy ,I`m looking elsewhere to get the work done . another dealer said I should stay away from a fully synthetic oil . I was told if I like to give it a bit of stick (drag racing ect ) a fully synthetic oil could cause clutch problems . can anyone give me an opinion please ??????

Motul 5100 10W40. Problem solved

Some dealers will recommend fully synthetic because it costs more and therefore their margin is better. If you run a heavy truck for huge distances, then a fully synthetic is worth it due to the extreme conditions. Little moto-siccles don't go that long between changes and very few riders put much of a load on the engine.

Suzuki says:

"Oil quality is a major contributor to your engine's performance and life. Always select good quality engine oil. Use of SF/SG or SH/SJ in API with MA in JASO.
Suzuki recommends the use of SAE 10W-40 engine oil. If SAE 10W-40 engine oil is not available, select an alternative according to the chart."

The chart merely shows temperature ranges, so with the climate in WA it probably makes sense to go to a 15W-50 rather than a 10W-40.

That information comes straight out of the workshop manual - so if it was necessary to run synthetic or even semi-synthetic wouldn't they say so there?

Following the information about SF/SG etc. etc. is more important than anything else.

Yes, additives in *some* car oils can cause issues with bike clutches.

Of course the option for anyone with more money than sense is to go for a Motorex fully synthetic, but then you'd have to have rocks in your head.

I run full synthetic...no real reason as it doesn't seem to make any appreachable differece. The synthetics to steer clear of are the car ones that have a friction modifier in as they will make the clutch slip.

I am using Fuchs Silkolene comp 4 10w-40 atm but it is no better or worse than any other motorcycle specific synthetic IMO and the cost is nowher near as expensive as the motorcycle brand specific ones. Some swear by Diesel engine oil as it has detergents in it I've never used it so can't comment.

Switched to full synthetic last oil change. Had to satisfy my curiosity. Used Motul 7100.
No difference performance wise. As others had mentioned in other related threads, I did find engine noises were a tad louder. Not of the bad kind though.
Curiosity sorted, I will be switching back to my old faithful Motul 5100 semi next oil change as I see no benefit in paying the extra $20 or $30 per change for the full synthetic as I change my oil on average every 8 weeks.

Your not going to find any benefit in one oil change. The benefit is in the life of the bike if you ride hard in extreme conditions.Any good brand oil will be ok with regular changes. The best thing for any engine is regular oil and filter changes including air cleaner.
I don't do that many km's so I can afford the more expansive oil. I use 300V even in the tractor(DRZ400). Nothing like the good oil!

I don't use the motorcycle oil in the Busa, however, I do like the Zinc

I seriously doubt any difference over the life of the bike between high quality oils be it full or semi synthetic. As I also subject my bike to stop/start commuting and the heat associated with it, I was mainly interested in any difference with reduced sheer down. Found no difference.
300V. If you ride your 'busa on the street hard enough, long enough to get an advantage out of 300V then the motor will last forever as you would have no license and possibly no freedom.
If you are talking purely track bike, then yes, 300V would be superior.

The great oil debate, it's like the great tyre or chain lube debate!

That is because people naturally resisting any changes. Including these resulting from getting more education on the topic

Hi Harry, I sell oil for a living and you are welcome to call me at work during the week 03 9555 7510 all these bikes must run a synthetic, but it must also be suitable for a bike, that is the catch. Bike oils have no friction modifiers or the clutch will slip. Anybody who tells you not to run synthetic oil knows nothing about oils.

Firstly there are plenty of synthetic oils without friction modifiers so there are no any catches and second, your statement -"must run a synthetic" is a complete rubbish coming from an oil salesman. Any oil meeting SF-SJ with MA in JASO specs is absolutely fine. Most of the riders here use semi-synthetic Motul oils and few mineral oil as well and we haven't hear yet an engine failure from using a non synthetic oil on this forum. Looks to me like it is you who knows nothing about oils which is surprising for someone who sells it for a living

Coming back permanantly in just under two weeks. Stuff following inc Busa...we are renting a place in Falcon for about six months until we find either a block in Perth we can develop or a bigger one at the right price to build on.

May end buying an established if the right one comes along. Will be sans internet for a while soon and if II friggingusless net perfom as they did when we moved here then that might be extended to the six months...missus has an internet phone that can be used as a modem so will be able to do posts etc but little else.

Will be in touch when the bike gets over for a few rides.

Has there been a debate about oil before?

Oh, and for the record I like rubber tyres and slippery chain lube.
