Sure, you can use Rotella 15w40 in the bike…. however, only use it when the temperature is no more than 40 degrees though. I have personally used several brands of 15w40 in my bikes for the past 10-15 years now.
Is it OK to use 15w40 instead of 10W40?
Viscosity or thickness of the oil increases with rise in temperature. A 10W40 oil will be thicker in the cold than 15W40 oil, but they will have the same viscosities at higher temperatures. The winter viscosity number dictates cold-start performance. … 10W40 oil will perform cold starts better than 15W40 oil.
Is it OK to use 15w40 instead of 5w30?
5w30 flows better than 15w40. 5w30 provides best cold start properties. Using 15w40 instead of 5w30 will increase your fuel consumption because of more load on your engine’s crank. No it won’t blow off,you will just wear your engine out quicker because the oil won’t flow to the moving parts as quickly !
What is 15w40 oil used for?
ADVANTAGE 15W-40 HEAVY DUTY DIESEL ENGINE OIL can be used with complete success in over-the-road diesel trucks, off-highway diesel equipment, farm tractors, and passenger cars and light trucks with diesel, turbo-charged diesel engines, or gasoline engines and is backward compatible with previous API Oil Categories.
Is it OK to use 15w40 instead of 10W30?
Yes, although it would flow slower when cold but not enough to make much of a difference as long as outside temperatures are above 50F it will also burn less if the motor is using oil but if the motor is solid and not smoking it’s best to stick with the 10W30 oil but a 15W40 would work if it’s all you have.
What is the best 15W40 oil to use?
For anyone who needs a good diesel motor oil to help boost their engine’s performance and fuel efficiency, we recommend the Royal Purple 15W-40 Oil. If you want to save some cash and still invest in one of the best diesel oil’s on the market, go for the Shell Rotella T6 Synthetic Diesel Motor Oil 5W-40 CJ-4.
Is 15W40 oil thicker than 30 weight?
It is the same thickness as the 10W-30 at operating temperatures. The difference is when you turn your engine off for the night. Both oils thicken over the evening and night. They both had a thickness, a viscosity of 10 when you got home and turned your engine off.
Which oil is thicker 5W30 or 15W40?
The number after the – specifies that the oil’s viscosity when hot falls into a specific range. So 5W-40 and 15W-40 both fall within the 40 range when hot, but 5W-40 is thicker than 5W-30 when hot. When the ranges denoted by the numbers, oils can vary in viscosity.
Is diesel oil bad for gas engines?
Diesel oils have to put up with much higher engine temperatures, higher oxidation rates, sulfur deposits, fuel soot, acids and other deposits and conditions not usually found in automobile engines. …
Is 15W40 thicker than 10w30?
Because 10W-30 is thinner than 15W-40 oil, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for a 10W-30 engine oil to protect as well and last as long as a 15W-40.
Which is better 15W40 or 20W50?
A 15W40 is going to have a much better aditive package and will more then likely be less volitile! 15W40’s usualy are shear stable were most 20W50 shear badly some down to a 30Wt.! If you want a good 15W40 Delo 400 and Delvac 1300 are the easiest to find and have excellent formulas.
Which is better 15W40 or 20w40?
so a 15w40 is as viscose as a straight 15 oil at 40c, but only thins as much as a 40 oil would at 100c. a 20w40 just tells you it’s a little more viscose at colder temperatures than a 15w40, but thins the same as a 40 would at the higher temperature.
Can I use 15w50 instead of 15W40?
15w50 will be fine if not better, it just means that the oil can withstand higher engine temperature than the 15w40.
What temperature is 15W40 good for?
“Diesel has the widest performance range with 5W40,” says Mark Betner of Citgo. “Its starting temperature range is down to minus 22 F (compared with 15-plus with 15W40) up to 122 degrees F (same as 15W40).
Is 15W40 good for petrol engines?
15w40 is typically used in diesel engines. … There are other additives to address issues particular to diesel engines but aren’t detrimental to gasoline-powered engines if the oil is used in them.
Can you run 10w30 in a diesel?
The lubrication manuals of all the major brands of on road heavy diesel engines allows for using 10w30. So worrying about OEM recommendation is not an issue.
