Conventional oils will thicken in cold weather and thin out when very hot, while the viscosity of synthetic is much more uniform. … High Mileage Oil: Vehicles are lasting longer, and more than 2/3 of the cars on the road have more than 75,000 miles on them.
Can you use regular oil after synthetic?
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.
What are the disadvantages of synthetic oil?

What happens if I put synthetic oil in my car?
Because synthetic oil does a better job of cleaning out sludge, it could remove deposits that are acting as seals. This could result in leaks that cause the engine to burn oil and require you to monitor your oil levels and replace it more often. If you don’t, you risk damaging the engine or other components.
Should I put synthetic oil in my car?
If you live in a region with very cold winters or very hot summers, or if you use your vehicle for towing or hauling heavy material, synthetic oil helps protect the engine from strain and won’t break down as quickly as conventional oil. If you have an older engine that’s prone to sludge buildup.

Is full synthetic worth it?
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. So if you can afford the extra cost, you should choose synthetic oil — and if your car requires it, you must use it.
What happens if I put 5w 30 instead of 5w 20?
Due to the increased resistance of the thicker 5W-30 oil, your engine will produce slightly lower fuel economy and horsepower output. You also risk engine damage when using 5W-30 instead of 5W-20, as the internal engine components are specifically designed to be used with 5W-20 motor oil.
