NOTE: A popular misconception when it comes to using motor oil, is “you can’t switch back to regular oil from a synthetic blend or even full synthetic”.

The reality of the matter is this, full synthetic is “man made oil”, synthetic blend is “man made oil with conventional engine oil mixed in”, and “conventional oil is the standard, from the ground engine oil”.


MAIN CONSIDERATIONS

COST OF THE FULL SYNTHETIC OILS

Cost can often times be a big contributor to a buyers decision on which oils to buy. We took a look at cost as a determining factor on whether a motor oil is worth getting, or not.

When you combine multiple engine care aspects such as using appropriate fuel system/injector cleaners to remove carbon deposits, quality octane boosters to help the fuel burn slower, and avoid any sensor faults which may cause efficiency to go out of wack (using an OBD2 scanner for this).. you will dramatically improve the overall life of an engine. That’s a proven fact.

Don’t forget to have clean engine coolant to allow your engine to run at an optimal temperature. Without a good running temperature, engines can become ruined.
