Typical skewer piece - a lot of "man the in street" and "expose" of what low-end employees are saying about the product.
I have owned and driven 4 cyl turbo cars since the early 1970's. I have only used premium fuel in my turbo cars.small turbo charged engines really do need the higher octane to prevent pre-ignition (what Octane measures) of the gas vapors. The turbo increases the effective compression in the cylinders, which increases the chance of uncontrolled fuel ignition. Higher octane reduces this chance.
I run 91 octane simply for drivability. I suspect the manual transmission drivers feel the difference in octane a lot more because the power difference changes when we shift.I use at least 91 most of the time, always top tier. But, I will not keep my car the full five years of my loan, so my thoughts are, what does it really matter. I'm not going to keep my car till it dies. And I have not found that my gas mileage is much different. I will do my oil changes religiously, and take care of my car. But whether I use 93 octane, and whether I use the Best oil, it doesn't really matter I believe.
My Eco 6MT does NOT show code KRD on my glove box list nor can I find that code anywhere on the interweb. Am I missing something?Here's the real test for your North American Cruze. Check the glove box list of codes. If you see KRD run 91 octane. KRD is the code that states the engine is designed for 91 octane, not 87.
Probably did the test when it was cold out. Heat makes a huge difference in how the car responds to 87.I have a '13 cruze like in the video and I get 10%+ more MPG using 93 over 87.
Not sure what they did wrong? Perhaps they didn't wait long enough for the engines computer to fully adjust to the higher octane fuel?
It is not just with 87. In Cincinnati, we have 3 choices 87 89 and 93. 87 forget it I may have used that for the first few weeks when I bought my car, 89 is not too bad but I can still notice difference (MPG and power from 93) Last 2 tanks have been 89 and both @ 30 MPG. 93 it feels like the car is alive again.
For the dyno test, both were wearing long sleeve shirts. The host was wearing an undershirt. "Mr. Expert" was wearing a coat. I think it's safe to say it wasn't 90F out. Probably not even 80F.
