I think your lawnmower engine posts are both interesting & informative Bing. The lawnmower engine makes for an effective prototype for all gasoline engines, and is much easier to experiment with than a car engine. Prototypes are a common practice scientists use when wanting to make the best use of their resources when studying a topic.
I do concur w/ @Nevada_545 's apparent objective of attracting more first time posters here, but banning lawn mower engines from the discussions here seems the wrong way to do it.
Iām not going to suggest lawnmower discussions be banned however the OP has an Acura, how many times should Bing offer lawnmower advice? If you want to hold your own discussion start a new one.
Iāve never used those, but I do use some bicycle-repair forums. While the answers do tend to wander, and thereās a lot of useless in-forum debates based mostly on the posterās ego , usually if Iām patient enough thereās someone there who will post something informative. I may have to wallow through 20 impertinent posts and personal insults first. But thatās the price paid for āfreeā information.
While using less than Premium High Octane gas will probably never damage your engine as the ECM will probably adjust, using lower octane Regular will reduce the additional HP on the vehicle that you paid for.
So why would you pay the extra big bucks for the the high performance turbo charged engine if youāre going to cheap out on the gas and end up with lower performance?
One motivation might be the car payments are making you are low on cash, so you have to reduce spending on something else to bring your budget into balance.
I canāt count the times Iāve heard someone say they canāt afford to do all the maintenance on their car. When in fact people afford what they want to afford.
What is almost worse is the people that run 89 or 93 octane when the vehicle calls for 87 octane, same thing but in reverse, now the engine is less prone to spark knock so the engine advances the ignition timing more than needed for optimum performance and fuel economy, and they get reduced fuel mileage nowā¦ Run what is recommended for the vehicle, no matter if 87 or 89 or 93 octaneā¦ If you need a higher than recommended octane fuel then something is causing your engine to spark knock, like to much carbon build up etc etcā¦ (in a stock engine)
Yes, but some people have very strange ways of āsavingā money. A friend of mine was always complaining about being short of cash, but instead of making a peanut butter & jelly sandwich at home, for her lunch at work, she bought Uncrustables, which cost a LOT more. When I pointed-out the price differential to her, she said that she didnāt have enough time each morning to make a PB&J sandwich.
Huh?
This was the same woman who used to tell me that she āsaved moneyā by paying for everything with cash, instead of using a credit card. But, because she always drove her gas-hog Buick to the bank at least two times between paychecks in order to get more cash, she clearly wasted money that she could have saved by paying with a no-fee credit card.
In Chicago at the last Shell station I went the difference was a $1.40!
$3.89 vs $5.29.
There is no way premium would give better gas mileage than regular if the car does not require it.
Totally agree. Using regular in a premium required car would probably knock like crazy. And possibly ruin it.
I previously had a Focus ST that only required regular but recommended premium.
One day I had a trip from Chicago to Harrisburg PA. It was all toll roads and same weather conditions throughout. Same Sunoco stations all the way. So I tried both regular and premium along the way. No difference in mileage.
My Escape now has the same engine. So I just use regular.
That is what the knock sensor is for, it should/will pick up any preignition (spark knock) before you will ever hear it and retard the ignition timing to prevent engine damage, but retarding the engine presents even more issuesā¦
