Whats a good oil, in your opinion ??

[tl_tub]

I can’t give advice, but I used Mobil 4T in the 250 Katana and even with scored (enough to dig your nail into) cylinders I never had a problem. Never lost any oil, always had great compression, and was always happy with the operation of the clutch under high rev take-offs. It isn’t cheap, but I prefer the piece of mind that comes from using a top shelf product from a company that invests huge amounts of money in R&D.

Has anyone really noticed a real difference in oil brands etc. I've seen so much writen & stated by various sources over the years, but can anyone categorically state that so & so ran his kamakooza V1000 on Suds brand oil & the thing blew up after x km while so & so ran his on greasy spoon full synth oil & it did 10 guzillion kms.
Most of what I've seen written is from anyhing but independent sources. Over the years, (& I'm talking 35 here), I've used Duckhams, Castrol, Bel-Ray. Motul, Putoline etc & many various types & viscosities & never really noticed much difference. I'd venture that as long as the oils reputable brand, & your only using it for street, (even if you think your Mr Gung-ho street racer), then how often you change it & the filter probably has more importance. For racing ???

The reality is, non of us flippin know & anything anyone of us says is full of it

vifferman, yep I agree. Its my 5 years of personal experience with my cage... so doesn't apply to bikes... and just to clearify... "Redline" is a brand of oil Redline oil

Motu, know what u mean. I have seen it too... and most people stay out of the topic... cause it goes on forever.... I rather have pressure & highest film strength for oil in my turbo motor. Cause I run either 15W50 for winter or 20w50 for summer, flow is not an issue when the engine is warmed up. The normal exhaust temp for that car is around 650 degrees, and when going hard can reach 800 degrees. So the need the pressure to get the oil into the turbo bearings.....

I have used Mobil 1 in all my bikes and cages and have never had any problems. In our TQ we ran Mobil 1 and never had clutch slip. Plus the motor would get so hot that the exhaust would be red hot to the last baffle plate on the supertrap muffler, and when I took the rocker cover off there was no burnt oil/carbon on the head. Tried other oils but always went back to mobil 1.

well.... its a common conclusion from guys on SDU that if you have a oil pressure sensor on your motor you'll read lower pressure if u are running Mobil 1. Mobil 1 might be good for small motors... but not big motors....
and I do get a smoother motor from running redline than Mobil 1...

The smallest motor I've ever used it in was 1100cc(ish). OK the McIntosh is only 1075cc but it's turbo'd and gets hot enough to make any oil on the outside of the engine smoke even after a cool down lap.

Gear shifting and clutch action on my bucket got noticeably better after I started using Motul Transoil, other than that I haven't ever noticed any differance in gearbox action with different oil.

Agree with comments regarding redline oil, mate uses a straight 60 racing oil in his drag car and has never had an oil related problem, apart from it escaping a bit now and then.

They're all good, just some are gooder than others.

Use ether Castrol 4T (minerial) or GPS (syn) depending on my mood but ownly use oil made for a 4stroke bike & change with filter every 5000Km - 6000Km. Only time will tell if I'm doing the right thing.

Yea mate, that 4t Active stuff is pretty good - I was running it in the ZZR no problems, go steal some motul 5100 when you feel like being rich - and see if you notice the difference very well.
