SAE 30 motor oil is commonly recommended for use in a lawn mower engine, but the safest best is to use the type of oil your lawn mower manufacturer recommends. Often 10W-30 or 10W-40, the same motor oil types that are used in vehicles, can also be used in a lawn mower.
Is it OK to use 10W40 instead of 10W30?
Changing from 10W30 to 10W40 will not do any effect on your engine if you choose right one for the right season. Its totally safe you can go for it. Look at the owner’s manual that came with the vehicle and follow it’s specifications.
Can you use 10W 40 in small engines?
10W40 does not meet the requirements for small engines. And SAE 30 is on the way out as being recomended. 10W30 & 5W30 are the recomended oils now. The reason is the additives and how well they lubricate.
Is 10W40 the same as SAE 30?
The difference between 10W-30 and a 10W-40 is the high temperature viscosity. Obviously, a 10W-40 is thicker than a 10W-30 at high temperature. … Using the correct viscosity oil eases starting, reduces friction and slows wear.
What is the best oil to use in a lawnmower?
SAE 30– Warmer temperatures, most common oil for small engines. SAE 10W-30- Varying temperature range, this grade of oil improves cold-weather starting, but may increase oil consumption. Synthetic SAE 5W-30- Best protection at all temperatures as well as improved starting with less oil consumption.
Which oil is thicker 5w30 or 10W30?
10w30 is thicker than 5w30 because it has a higher viscosity in low temperatures. The engine oil will flow slower than 5w30 during the cold season. Thicker or higher viscosity metal oil has a better seal compared to low viscosity oil. Thicker oil offers better lubrication of motor and engine parts.
Which oil is thicker 5w30 or 10W40?
A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.
What does 10W40 mean?
The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100°C. This is a fixed limit and all oils that end in 40 must achieve these limits. Once again the lower the number, the thinner the oil: a 30 oil is thinner than a 40 oil at 100°C etc.
Can I use SAE 40 instead of SAE30?
Naji Abou-Haydar has a very good and concise answer, but most SAE 10W-40 oils will work perfectly in an old engine designed for SAE 30. Some old engines makers claim that this will not work, but our experience over many years confirm that there will be no problems.
What’s the difference between SAE 30 and 10W-30?
SAE 30 is an oil that has a viscosity of 30 at overly high temperatures. The 10W30, on the other hand, has a grade 10 viscosity at low temperatures and grade 30 viscosity when the temperature is high. Therefore, the 10w30 is ideal for varying temperatures since it has the grades for any temperature condition.
What happens if you put 10w40 instead of 5w30?
If you use 10-w-40 instead of 5-w-30 specified by the manufacturer then the viscosity of 10-w-40 used by you will be higher and oil thicker than what is specified during winters. Similarly the oil viscosity will be higher and oil thicker than specified during summers.
What does SAE 30 oil mean?
SAE 30 oil is a motor oil that has been given a viscosity rating of 30 by the Society of Automotive Engineers, according to AA1Car Automotive Diagnostic Help Center. Motor oils typically have ratings from 0 to 50.
Can Briggs and Stratton use 10w40?
You absolutely can! It’s usually a better idea to go with SAE 30 or the lawn mower oil recommended by the lawn mower’s manufacturer, but it more than likely won’t be an issue if you use 10W 40 oil instead.
