5100 4T 15W-50 Motorcycle Oil - Technosynthese Semi-Synthetic with Ester - API SP JASO MA2 Wet Clutch Safe - Heavy Duty Engine and Gearbox Protection for Street ATV UTV Adventure Bike 1L

As advertised, Motul 5100 Ester Blend 15W-50 (semi-synthetic) appears to be optimized for a shared-sump motor. I immediately noticed a quieter valve train with my Triumph air/oil-cooled motor. I have recently experienced clutch chatter during high operating temperature in slow speed maneuvering and clutch slip at takeoff prior to reaching full operating temperature. That has seemingly disappeared. Gearchanges are now accompanied by a "snick" rather than what had developed into a soft "clunk". As the miles have piled on, the transmission, although exceptionally smooth compared to many other modern machines, became slightly reluctant to shift smoothly. That has also now seemingly vanished. This particular machine calls for Semi-synth or full synth, shared-sump oil in either 10w-40 or 15w-50 weights. In Southern California, the "winter" weight of the oil is a non-issue, so I have taken liberty in the past with this. The previous fill was with Mobil 1 Racing 4T (PAO, or so we've been told) 10w-40, an oil that I have used for years with little complaint. If anything, my previous fills with Mobil 1 have felt like they are shearing down before 3-4000 miles, well before the recommended 6000 mile interval. In this machine, a previous Triumph twin, and other machines, I have filled with Redline (ester) 20w-50 & 10w-40, Mobil 1 4T 20w-50 (PAO, or so we've been told), Castrol Actevo (semi-synth) 20W-50 & 10w-40, and Castrol Power 1/RS (Group III) 10w-50, plus some others I fail to recall. All of them are fine oils for the application. At some point, the Mobil products resulted in clutch chatter and slip. At some point, the Castrol products seemed to shear down around 2-2500 miles. The Redline products never gave me an issue other than 1) locating some and b) paying the asking price. Motul 5100 is priced more competitively than all but the Castrol Actevo. However, Motul 5100's ester synthetic base and additive package is available at a price point that the competition doesn't offer. For the quantity, this oil is quite a bargain. Although not readily available at an auto parts store like Mobil, Castrol or Valvoline motorcycle oils, telegraphing an oil change and having oil shipped is a minor inconvenience in the context of the benefits of Motul. Frankly, I've avoided Motul for this reason, as well as the fact that they market so hard for independent shops to carry the product line. Having worked as a motorcycle mechanic for a spell, Motul products seemed cheap for this reason, despite being able to buy at cost. However, customer comments on how much better the motor "feels", even with Motul's standard mineral product, should have clued me on. I guess I was ignoring how much harder the huge companies market their motorcycle products to chain stores. So much for standing on principle... Whether Motul 5100 shears down quickly in this bike remains a to be seen. I'll add to this review when I know more. Hope this helps you make a good decision.

Motor is quieter. Exhaust volume seems quieter. Neutral is found much faster. Shift into first while cold no longer clunks or lurches as did with Honda GN4. This is a superior product! CRF250L is the bike, operated in hot weather in Japan.

i use this oil in my zzr 1200 and no motor issues also use in my gpz 1100 with 120 thousand miles since new in 1996 and still runs great with no oil burn

Great product and exceptional value for the money

It's motor oil - I got this for my Royal Enfield Classic 350 so I didn't have to drive 30 minutes away to my nearest shop. This is Motul brand motorcycle oil, it's good stuff.

On time and a great value. We only buy motul products

Works good on my Ktm duke 390 it runs smooth. I still have 2liters left for the next oil change and after that i will try motul 7100 full synthetic oil.

works

Die Lieferung erfolgt schnell. Das Produkt ist gut verpackt und macht keine Probleme, kann ich nur weiterempfehlen.

I bought this for my motorcycle, and it works well. It's easy to use, and the bottle shows the level so we can track our usage.
