Which is thicker 5w30 or 20w50?
20w50 is actually thicker than 5w30. This will result in less fuel efficiency, less horsepower, and more engine damage because it will have to work harder to rotate.
Can you use 20w50 oil on a motorcycle?
Both of these benefits extend engine life. Depending on the recommendations for the particular vehicle, 20W50 oil is suitable for large or small diesel engines, gasoline engines, motorcycles and aviation vehicles. It is also suitable for both air- and liquid-cooled engines.
What happens if I put 20-50w oil in an engine that needs 5?
A 20W/50 oil is much thinner at high temperature than a 5W/30 at a low temperature, so the viscosity will not hurt your engine. BUT and it is a big but! Most 20W/50 oils do not meet the anti wear requirements of modern engines! You must look at the API logo and confirm that the oil meets the minimum specified by the manufacturer.
What kind of oil do you put in an old car?
So in old engines the manual might specify 30SAE oil which was a compromise between oil thin enough to run in the engine when it was cold, yet thick enough to provide lubrication when the engine was running hot. Chemists invented additives to oil that change the oils viscosity with changes in engine temperature.
Can you use sae30 oil in a lawn mower?
The thicker viscosity of 30 weight oil assists air-cooled engines to keep them running… cooler! SAE30 is very suitable for older, aged engines to use. 20w50 will work in engines for what could be described as the summer weather period.

What’s the difference between 50w50 and 40w50 oil?
The ‘50′ part is largely irrelevant as it has essentially the same viscosity once hot as a 40. All engines are designed to run on oil that has heated to and is as ‘thin’ as water. The longer your oil takes to get that thin, the higher the engine wear. the smaller the engine the harder that engine has to work, so the more extreme the early wear is.
Which is better 10W 30 or 20W 50?
It really comes down to personal preference. As your engine does put out significant horsepower, we would lean toward using 20W-50. If your engine sees very light duty or is built exceptionally tight, 10W-30 would be fine. But again, if you twisted our arm, we would give 20W-50 the nod for the thicker viscosity.
