Who are you?

 

Here we go again. Explain semi-synthetics slick.

 

My theory is this, you bought the cheaper oil and at high operating temps the viscossity of the oil became thinner which allowed the engine internals run a little easier but dare you try to rev the engine or race with it, you can expect a new engine very soon.

Thinner oil makes an engine run easier but isnt always better. Only thing you'll get is maybe an initial mpg increase but also an increased wear on the engine internals. I'd go back to the oil you used before.

 

What to do you mean? Thats a weird question.

 

He's not gonna listen to you alloyic rs its a lost cause. I mean look at his name.

 

Arguing with noobs is pointless.

 

yeah good point

 

i use the same gas 93 every fill up and run my car slightly hard often and get about 300 - 330 miles per tank of gas.... i cant figure out why.

 

That was a good one. Yeah i may not have over 100 posts and may be a noob to this forum but that doesn't mean i just got my car. So what, its not the end of the world that i'm a noob to a specific forum and it also doesn't mean that your right just because in am a noob.

 

Thats because your car doesn't require 93 octane. If it doesn't reccomend using a higher octane in your car its because if you do use a higher octane it won't really make a difference. But running it is ok and it may burn cleaner but it won't have much effect on your mpg.

 

yeah it will. The higher the octane, the better it burns=better mileage. its about an equal trade off, you get more miles but pay more, the lower the octane, you pay less but get less miles.

 

hmmmmm. thats not true. read octane myths just a bit down the page.

Ummmm once again you don't entirely know what you are yapping about. High octane gas locally (since you cited a MN doc) is non-oxygenated gas in about 75% of the stations outside of the twin cities. Non-oxygenated gas has been proven to produce better mileage and is probably a good reason for why people automatically think the higher octane gas = better mileage, when it is not always the case.

 

Yea, umm, its time for you to shut up. i don't care.
