If I start using synthetic motor oil can I switch back to conventional oil in my vehicles engine?

It's really not recommended to switch back and forth between synthetic and conventional motor oil. Pick one and stick with it.If I start using synthetic motor oil can I switch back to conventional oil in my vehicles engine?
Here's the scoop on synthetic oil. It is far superior to regular oil, it lasts much longer, lubricates much better, especially on cold start ups in winter. A car when bought as NEW, should first be broken in with REGULAR oil. And continue using regular oil for between 5 and 10,000 miles. --at that time, you may switch to synthetic oil untill your car gets very high miles like 100,000 and up. At that ime you may wish to return to regular oil. ---This is because synthetic oil is smoother and thinner, and may leak from a ver old and worn engine. Likewise, when the car is NEW--no miles..it NEEDS regular oil to BREAK IN the engine. And because regular oil is not as lubricative as synthetic, your new engine needs it to break in properly before switching to synthetic. If it is done this way, the synthetic will greatly extend and protect your engine for the majoriyt of it's life. I also find my gas milage has increased by a mile or two per gallon by using synthetic. On cold mornings, regular oil takes time to thin out and fully lubricate the engine. Synthetic oil is ready from the start, even at 0 degrees. It instantly protects your engine right from the start when you turn the key. The synthetic oil instantly runs to every nook and cranny of the cold engine, protecting your engine for many years from cold start ups, which can wear critical parts in the inner engine. It is not recommended to switch back and forth over and over between the two oils. Once your car is fully broken in, and the synthetic switch is made, yuo should continue to use it for the long haul untill your engine is old and worn, creating bigger gaps in the engine from natural wear---then the switch BACK, later in your engines life, may be needed to stop the thinner more lubricative synthetic oil from dripping from the worn engine...over all, synthetic oils, when used on this skedule, will vastly protect your cars engine, and likelu extent its life.If I start using synthetic motor oil can I switch back to conventional oil in my vehicles engine?
yes... those synthetic oil requirements are basically a scam. The company will say that the car was designed for it, but the computer on the car will actually compensate for the different viscosity and oil properties. If your worried about the mineral loss in the engine, there are treatments you can run every 20000 miles that will restore the minerals. Probably far cheaper then synthetic oil in the long run.
synthetic is actually cheaper to run if you factor that you can go 12,000miles between oil changes. i pay about $7 a quart for royal purple and use 6 quarts that is $42 for an oil change another $10 for a good filter so $52 dollars for 12,000 miles. good regular oil is about $2 a quart, i need 6 so $12 and about $4 for a filter so $16 per change for 3000 miles $16 time 4 changes to equal 12,000 is $64 per 12,000 miles





so $52 per 12,000 synthetic


and $64 per 12,000 dino-oil
Yes you can, but make sure you use the same grade.
Yes, you just need to do an oil and oil filter change.
