What gas do most use? Can you use regular unleaded or have to use premium?
We’ve always used mid-grade gas in all our hemi powered vehicles for that reason.If you look in your owner's manual, you'll see that the 5.7 can use 87, but 89 is recommended.
Also, we have an excellent search feature; it's always good practice to see if something has already been covered.
I'll typically go with what the recommended octane is.
welcome from Louisiana.
I use middle grade about every 4th fill up in my Hemi, do not notice any difference but should help keep the engine cleaner. If you can find non ethanol use it.
Welcome! That color really pops! I use 89 in my RT, for the reasons others have listed above. Unless your car has had a 91 octane tune or the like, running higher than 89 is just wasting $$. Save the $$ for more mods! Lol
Damn, all the stations around me have 89 as the premium.Welcome! That color really pops! I use 89 in my RT, for the reasons others have listed above. Unless your car has had a 91 octane tune or the like, running higher than 89 is just wasting $$. Save the $$ for more mods! Lol
What’s the point in doing that?I believe the 392 and hellcat require premium gas. Since my '19 Daytona 392 is not a daily driver but basically a toy I use 93 plus a little boostane
I have mostly run my 2013 Daytona R/T Road and Track with 87 octane with no performance issues. I put so many miles on it that the extra $0.30/gal just seemed too expensive when the manual says 87 is OK to use. It has almost 134,000 trouble free miles. I have run 89 in it at times when I felt guilty not using the recommended octane. There is no noticeable difference in driving it or in any sounds coming from it. Now if I take it to the track, I will let it get below an 1/8th tank and fill it up with Sunoco 93. It runs pretty good with whatever octane is in it!

Damn, that stinks, Slickwilly. Lots of 91 octanes around here, and locally, VP Fuels sells 93 for just 20 cents more than 89. If I ever get it tuned for 93 octane, I'll gladly spend the extra 20 cents! But it's a stock tune right now.
