Using synthetic and standard oil on engine?


How does changing oil back and forth from standard to synthetic affects car engine

You can switch back and forth between conventional, semi-synthetic, and full synthetic as much and as often as you wish. The &quot:once you switch to synthetic you can never return&quot: ultimatum is a myth. While some synthetic oils do contain special detergents and additives to maximize performance, none of them are capable of altering the molecular composition of your engine to require it to continue to need synthetic oil forever. They simply lubricate your engine, and lubricate much longer and more efficiently than conventional oils.

Synthetic motor oils are fully compatible with all petroleum motor oils, and there is no danger in mixing the two. Essentially, that is exactly what synthetic blend or semi-synthetic oils are, a mixture of full synthetic and petroleum oils. Mixing with petroleum oil, however, is not recommended as a general practice. Performance and long drain intervals will be sacrificed, defeating the advantages of full synthetic oils.

It is a common misconception that changing to a full synthetic oil will cause the engine to leak. In modern vehicles, there is no risk of full synthetic motor oil leaking. In fact, most synthetic motor oils are fully compatible with modern seal materials. AMSOIL, in particular, is properly formulated to condition seals, keeping them pliable to prevent leakage.

Another common misconception is that changing to a full synthetic oil will clean and loosen sludge from the engine and cause it to plug the filter and passageways. This too, is false. Switching from petroleum oil to full synthetic oil in routinely maintained vehicles will not cause clogged oil filters or passageways, regardless of mileage. Sludge, which is caused by poor quality oil and neglected maintenance practices, would have to be present in significant amounts to plug oil filters and passageways. If this excessive amount of sludge is present in an engine, it is just a matter of time before oil filters and passageways clog, regardless of the installation of synthetics.

There are no special procedures for changing from conventional oil to full synthetic oil, but as a precaution in older vehicles or those with high mileage, it may be advisable to use an engine flush first. This will ensure that the engine is clean and free of any accumulated contaminants which might have an effect on the service life of synthetic motor oils.

Full synthetic oil is better for any car for several reasons. The detergent additives are stronger so the inside of the engine will always be clean. It remains more fluid at reduced temperatures for easier starting. The oil pump will force a greater volume of oil to frictional surfaces quickly at start-up. The EP (extreme pressure) additives are better which protect cam lobes and lifter rollers or the flat surfaces on the bottom of some lifters. Low viscosity synthetic oil will run cooler with less friction in any engine. You’ll get better fuel economy. You can safely drive more miles between oil changes.

Major oil companies say that you can swap back and forth between the two types of oil if you so choose.

it doesnt… unless….

you have a high mileage engine, that has always used normal organic oil, then you use synthetic. the organic oil will sludge around any leaks you might have, thus preventing it from leaking in the first place. When you change out to the synthetic, it will clean the sludge out, and sometimes will clean the sludge out from where there are leaks that were plugged by sludge. Therefore, resulting in oil leakage.

agree with nomad. synthetic is real good for an engine and will last longer then convintional oil. u can run synthetic oil to no more than 5000 miles, i do, and its still good.

Should not be a problem until your vehicle gets 10 years or older, and/or more than 75,000 miles.

Then – Switch to Valvoline Max-life synthetic blend and – not to worry.

your indecisiveness between the two will kill your engine eventually. Synthetic oil is a good option though.

I don’t know what it does, but I know it isn’t good. It depends what your motor needs, should say in the driver’s manual.
