With that in mind, it is easy to understand that an oil with 5w in the rating will offer better low temperature performance than an oil with 10w in the rating. This is because, regardless of their viscosities at operating temperature, 5w oil will always be thinner than 10w oil. The 15w40 engine oil has excellent high thermal and oxidation stability. Temperature: The design temperature of 5w40 engine oil does not exceed 5 degrees. The lowest temperature you can expect from 15w-40 engine oil is 15 degrees. Price: The 5w40 oil price is around $48-$52. The 15w40 oil price is around$37-$42. On the last (annual) oil change, I put 10W-40 in, and it puffs a little smoke each time I rev the motor from idle to running speed. Unlike a pump-fed car's lubrication system, small lawnmower engines are lubricated by splashing oil with a dipper connected to the crankshaft. Consequently, it doesn't hurt to run SAE-30 or SAE-40 oil, even in cold Viscosity is the thickness of oil at a given temperature. As temperatures increase, viscosity increases. The 10w40 is considered to be less viscous at higher temperatures when compared to 15w50 oil. What this means is that the 15w50 will perform a lot better in higher temperatures. The Bel-Ray EXP Synthetic Ester Blend 4T Engine Oil SAE 15W-50 and Thumper Racing Synthetic Ester Blend 4T SAE 15W-50 are both premium lubricants and share very similar formulations, but the Thumper formula was specifically made to address certain concerns better with single cylinder off-road applications that have a low volume of oil (less If you aren’t running your lawn mower in really cold temperatures however, there’s no noticeable difference between using 5W 40 oil instead of 10W 40 or SAE 30. 10W 40 and 5W 40 are just meant for warmer climates, so as long as you aren’t mowing the lawn in temperatures below -30 Celsius (-22 Fahrenheit) you’ll probably be okay. I use 15W-50 4-stroke oil in my dirt motorcycle. We have some 15wt RS oil. My 15W-50 automotive oil seems noticeably thicker than the 15wt RS fork oil just by pouring and rubbing the oil between your fingers. It makes me wonder what differences may exist between the rating systems between these two oils. I would have anticipated that they were For 4-stroke engines Castrol POWER1 4T 10W with Power Release Technology™ optimises friction which in return provides motorcycle enthusiasts with a superior acceleration at the twist of the throttle. Castrol POWER1 4T 15W-20W with Power Sustain Technology™ manages heat and friction in bikes, ensuring continuous power delivery through its THE 10W30 OIL & ITS BENEFITS. The 10W30 oil – While still quite “fluid”, this oil is a little bit thicker at low temperatures than the 5W30 oil, making the process of starting your engine a little bit harder. It is recommended for use at -13°F up to 95°F / -25°C up to +35°C (outside temperature). The difference between 10w50 and 15w50 is negligible. Whichever oil weight is available at your local auto (or moto) parts store will work fine. Just make sure you buy the good stuff. With regards to the clutch, try bleeding it. If that doesn't work, take it back to your dealer and let them take care of it as a warranty (I hope) issue.
