Is it OK to switch from 10W30 to 5W30?
Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.
How long does 10W30 synthetic oil last?
No. Oil shouldn’t be used after a few years; the exact period varying between 2 years (according to Total) up to 5 years (Mobil).
Is it worth switching to synthetic oil?
Synthetic oil is more expensive than conventional oil but offers superior protection for your car’s engine. Synthetic oil provides more effective protection for your car, may even prolong the life of your engine and would cost the average driver just $65 more each year. …
Why can’t you go back to regular oil after synthetic?
Switching to synthetic oil causes leaks: Generally, switching to synthetic oil does not cause leaks. It is true that synthetic oil is thinner than conventional oil and therefore flows more easily. You can’t switch back to conventional oil: Once you switch to synthetic, you are not bound to it forever.
Is switching to synthetic oil bad?
Answer. Synthetic oils typically provide better protection than conventional oils, but switching back and forth between full synthetic and conventional oil will not damage the engine.
When to switch from 5W-30 to 10W-40?
In the summer a 10W40 just gets you a little less gas mileage. In cold weather, however, it takes a very long time for the oil to reach the valve gear on top of the engine. EXXON did a test with 15W40 and 10W40 at -35F and it took several minutes to get good lubrication to the valve gear. With a 0W30 synthetic, the oil flowed very quickly.
What’s the difference between 5W30 and 10W30 engine oils?
Both 5w30 and 10w30 engine oils are the same, but their difference is brought about by their viscosity. Both of the motor oils are multi-grade, meaning that they work well in both high and low temperatures. Let us now discuss things that make the two engine oils different:
What are the benefits of using 10W30 oil?
10w30 has different unique features and benefits. This engine oil forms a continuous layer over all the parts of the engine so as to reduce friction between them. They also reduce the wear and tear of the engine during the stop/start operation while keeping the engine cool. 10w30 protects parts of the engine from rust.
How many people use 5W 30 even though?
In general, there should be no problem with 5W-30 if you use a good quality synthetic. 2. Use 50% 0W-20 and 50% 5W-30 (or whatever percentages you want). My 2GR’s run 30 and 40 grades.
