93 octane worth my money?
 
so since its my brand new truck and all, i was thinking of spoiling it rotten with 93 octane gas every fill up. any pentastar mechanic super techs out there know if its a good idea? the manual says 87

87 will be best. Using higher octane than required is not only a waste of money but promotes carbon buildup and can actually decrease performance. You want to use the lowest octane possible without causing detonation/pinging.

Hopefully at some point a tuner will be available for that engine.

Yes exactly. Although the manual on my 2012 recommends 89 but indicates 87 is ok to use.

I used 93 octane in a car when I was younger thinking it was better, after about 6 months the engine would shudder and make a funny sound, like a metal on metal sound. I had it checked out and they weren't sure what was causing it, just for the hell of it that asked me what kind of gas I was using and I told them 93 octane and they said with confidence that's the problem, they called it ping.

Higher octane gas actually has less combustible material in it. So you will actuallu have a dirtier burn and make less hp and like the others say build up more carbon

Are you guys joking here???
On my Tacoma, that I just traded for the Ram, it Pinned with 87 Oct and rode so much stronger with 93! Used 93 most of time on it for 3 years, never had a problem, run stronger with it.... Only cost more....
How about all the claim that Shell has about their claims of Cleaner fuel, etc !!
So, is it just different with the Ram???
Your thoughts please!

Running higher octane power to money ratio is only worth it if you have a tuner to tune the engine to use that extra Octane, the power to money ratio just is not worth it without a tuner. The ECU will compensate only so much without a tuner
