CastrolActevo 4T 10W-40 Synthetic Blend Motorcycle Oil, 1 Quart, Pack of 6

Think you need synthetic?Castrol Actevo is a synthetic blend that runs exceptionally well and is a great value when compared to the costs of exotic pure synthetic oils. If you are trying to make up your mind as to your specific needs, consider the following..........1. The company that I work for maintains a fleet of about 25 light trucks and cars. In the thirty years I have been there I know that the engine oils are changed at 7000 miles. The only oil ever used has been and still is a multi-grade non-synthetic mineral oil. We ran vehicles to 100,000 miles until about ten years ago and because we have had such good luck with powertrain durability we upped it to 150,000 miles before replacement. To my knowledge, we have never had an oil related engine problem. Of course these aren't motorcycles but point being, regular changes of engine oil and filter is crucial to longevity of service.2. Google "Aviation oils" and you will find that piston aircraft engines are run on mineral (non-synthetic oils with synthetics used primarily in turbine and jet engines. Lycoming and Continental recommends engine breakin on pure mineral oils with no additives.3. Personally, and your opinion may differ from mine, but the way I determine if an oil is doing it's job in my motorcycles is to run a magnetic drain plug and a magnetic filter ring and after the initial breakin period where metal accumulation at the magnets is normal, if I continue to see powdered metal on the magnets after breakin I would consider trying oil of a higher grade.4. Most "synthetics" are not synthetic at all but are just more highly refined mineral oils. Generally speaking it's the additives that give synthetic as well as mineral oils their superior properties.In motorcycles, I don't agree with extended change intervals advocated by marketers of synthetic oils. I would not argue that synthetics in the laboratory are indeed indicated by testing to be superior to pure mineral oils and under extreme conditions they would be a better choice. But, I have read that 85% of users of synthetic oils will never need their capabilities. Your choice of oils is unique to your machines and your riding style and I would not attempt to argue for or against any oil (mineral or synthetic) but consider that "CASTROL ACTEVO" is in the middle of the road as a synthetic blend at a cost of around $5.80 a quart as compared to synthetics that are far higher priced. After you evaluate your needs, maybe you find that you really don't need those high tech engine lubricants. In shared sump motorcycles, I change oil/filter at 2500 miles and have never had an oil related engine/transmission problem using Actevo. I've been riding since 1968 and average perhaps 15,000 miles a year. All my motorcycles (four at present) are Jap shared sump motorcycles.Ride safe friends!

Works well in my 25 year old zharleyCastro makes quality oil, and this is that. Bike runs great and oil consumption is less than other oils.

Much better price than in the car store

Good pricing and clear spec qualification

Unfortunately Rotella full synthetic no longer gets along with my wet clutch motorcycles despite having the JASO MA ratings so I had to switch oils.With the 5w40 full synthetic Rotella I used to easily get 5,000 mile extended oil change intervals (up from 3,000) and had a slight increase in fuel economy (around 8 percent or so). Either the formula changed or maybe the age and abuse on the clutch is finally showing it self, but Rotella no longer agrees with my fleet of motorcycles.This Castrol is keeping 3 of my 5 motorcycles happy, nice smooth clutch and gear engagement, finding Neutral easily even on my Bashan 198cc Chinese motorcycle that usually has tough and notchy gears...I am however no longer getting the benefits I was getting with the 5w40 full synthetic oil, no more extending the oil change intervals and I'm seeing slightly lower miles per gallon with the 10w40 synthetic blend.But again, I no longer have gearbox chatter and wet clutch issues with this oil.I will be trying Valvoline and other name branded full synthetic Motorcycle formulas to see if I can get similar clutch feel and get better fuel economy again... 8 percent is a lot more smiles per gallon between that boring idle time filling up at the gas station after allWorking great in my 1999 KLR 652cc with 13k miles, 2013 Bashan Will 198cc with 5k miles, 2023 Lifan KPM 198cc with only 3 miles (just purchased and assembled the KPM a few weeks ago)

Great oil for my spyder

Factory packaged oil to be used in a classic, 2000 Triumph Trophy 1200 motorcycle. 20W-50 is best used in warmer climates where temperatures don't go below 45F degrees. This is oil for hot running engines in warm climates. Check your owners manual for proper oil in your motorcycle. Many newer machines call for 10W-40 weight.

I've used just about everything in my bike. Recently had Rotella T6 but bike shifting was really bad. Saw the price on this and thought why not? Hadn't used blended oil before.I'll stick with this from now on. Bike has never shifted as well.Great stuff at a great price.2019 Kawasaki Vulcan Voyager.
