Is that a personal opinion unsupported by facts, or is there compelling evidence that supports your opinion?

1. It is spec'd to use 87 octane gas. 2. When I downshift the compression braking is almost non-existent. With my Miata, downshifting would push you against the seat belt like you had hit the brakes. Consequently, the paddle shifters are of very limited usefulness. 3. Many vehicles that I have seen that have high compression engines have a tag that says something like "Premium Fuel Recommended". I would really like to have more technical information on the engine, but don't know where to find it. Sorry to waste your time; I should have used the search function, but got as many contradictive answers after looking at some of them as I got this time. So, who do I believe? |

11.5:1 is correct. Don't have time to find a link. But I have seen it before. Also, engine braking doesn't "feel" strong because the paddle shifters rev match downshifts to make then smoother and not "push you against the seat belt." Try this...in a parking lot or something, take M1 up to about 3500-4000 rpm and let off the gas. You'll feel that compression right quick! Lol. Sent from my bragging iPhone using an app that encourages it. |

And now they are merged. I wonder if he/she will visit now?

"Second, if the LFX V6 is a low compression engine () then your Miata had no compression." The Miata specified Premium was recommended due to the high compression. I disagree with the poster who suggested that I get up to 3500 RPM in M1 and let off the gas to prove that it is high compression. With the Miata I could be doing 50 mph, downshift one gear and feel the effect; I don't get that effect with the Camaro until I downshift in to M2 at about 2000 - 2500 RPM. That is why I said that the paddle shifters are not very useful for compression braking. Going back a few years I had a '60 Austin Healy that would throw me to the windshield if went from 4th to 3rd at 50 MPH (I don't remember the RPM's at the time as that was quite a few years ago). |

I have 4000 stall and I engine brake in mine all the time.
