I think synthetic motor oil basically....?

Question

makes a NORMAL $20 oil change cost more... AND does nothing to help your engine. I think it's a WASTE of dough!!!

Do you agree with me???

I've been using valvoline (regular) in my car for 402,000 miles - no probs.

Answer 1

It all depends on the desgin of the engine. If you are talking about most American and Japanese made engines that were designed for dyno oil and have somewhat loser tolarences, no, it doesn't make any difference.

But if you are talking about German engines, you'd better stick with what is requried. (usually synthetic) Many of those engine run at higher temperatures and tolarences (gap between piston and the wall) is 10 times SMALLER. Dyno oil will not properly lubricate it under high load.

In Germany, they have much stricter emission requirement. They run at higher temp to reduce the emissions. (newer ones anyway)

Answer 2

I think that if you are hard on your car (frequent start stop, on/off and running high RPM) that synthetic is the way to go. Im an extremely hard on my cars and always run a sythetic oil and never have problems. Synthetic oils have less additives in them, which means that they dont "breakdown" as fast or get as dirty as regular oil. Also with synthetic you dont have to change the oil as often, just change the filter every 2500-3000 miles still. I use Royal Purple oil and every oil change the oil is only a light brown color as opposed to a black color that you get from regular motor oil. So the money that you pay extra is more than worth it.

Answer 3

Synthetic oil is derived from regular oil (and recycled oil) but chemically refined to have far better shear strength an durability than "regular" oil. Regular oil is mixed with additives (up to 50%) to preform as necessary. Synthetic oil has very few additives because it started off proper. The choice is yours but eventually, when there is no more oil from the ground, synthetic will be your only choice.

Answer 4

Yep, can't argue with that.
