A decent race oil will take about 10 hours of hard track use and a semi-syntehtic or hydrocracked base stock will last about an hour before the oil begins to lose viscosity. Are 5w and 0w oils too thin? I read on many forums about 0w and 5w oils being too thin. 0w-40, 5w-40, 10w-40 and 15w-40 are all the same thickness (14 centistokes) at 100degC.
SAE 30 and SAE 40 are both single-grade motor oils that have been rated once at a high temperature. At room temperature, these oils will have a thickness or viscosity that is pretty similar, but when hot, SAE 40 will be more viscous than SAE 30. Because of this, SAE 40 is mainly used in high revving engines like motorcycles, boats, and cars.On the other hand, you may use a 5W viscosity grade where a 10W or 15W is recommended to provide faster lubrication to engine components during start-up. However, there are some drawbacks to consider. For instance, since a lighter base stock is used in the 5W formula, the lubricant may have more evaporation than a 10W or 15W.
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
Comparison Table Between 10w30 and 10w40. 10w30 has a high viscosity. 10W40 oil is more viscous in hotter weather. 10w30 motor engine is not suitable for low temperatures. 10W-40 engine oil is suitable for high temperatures. 10w30 has thick motor engine oil. 10w30 motor engine oil is suitable for heavy-duty engines.
Below you can find a equivalence suspension oil chart (both for motorcycle and bicycle) where you can easily choose the closest oil to the original one. Oils are sorted by Viscosity. SAE range is only shown for your reference. If you can’t find the same viscosity as your original oil has, choose one with a difference of +/- 5cst.
Since Plus-50™ II is a multi-viscosity oil, it is not recommended as it doesn’t meet both requirements noted (less than 1% ash and single viscosity). Q. I use Torq-Gard SAE 10W oil in the winter and Torq-Gard SAE 30 in the summer. Can I use Plus-50 II 15W-40 oil year-round instead of changing oil grades seasonally? A.rgWIxQs.
