People ask: Do you really need and oil additive?
Answer: The car makers so, no!
They say, the oil grade and weight - now usually 0w 5, 0w 10 for the last few years of new cars. However, the reality is yes!
Not all vehicles are new and pristine clean and operating at peak. Yet, tens of thousands of new cars fill every brand of dealership repair shops because friction ate away some part, caused an operating problem and needs replaced.
Us car buffs know if there is friction in one place, you can bet other engine places will have friction and show up as soon as the warranty ends - you have to foot that bill.
We don't know if our new car will be among the percentage that happens to or not. So we add and additive that has MC+, metal conditioner that removes raw friction to our motor oil.
That product is called Mega Power Oil Treatment $19.95. 12oz bottle treats 4 to 6 quarts motor oil capacity engines. We feell it should go in every oil change to stop friction even if there it no problem. And added to the new oil that comes in the motor. For most of us who use Mega Power Oil Treatment we feel it is what hass made our vehicles run 200,000 to 300,000 - 500,000 if a diesel trouble free. Ends hot spots and reduces oil temperatures by 10%.
Although car makers say, aftermarket oil additives are not required for your car to run, some usage like Mega Power Oil Treatment seem to provide significant benefits that improve the performance at the other end of the vehicle life. They help the performance and longevity of engines. Adds anti-wear to transmissions and differentials.
