New to the group and just purchase a 2005 SRT10 RC with only 6k miles.

as most of you know Prem. Gas is very high and yes I knew this when I bought it. The dealer indicated an a tank of mid-grade once in awhile would not hurt the engine.

Is that sound advice or should I stick with Prem always.

thanks
Mike

 

Is the premium gas were you live 91octane or 93octane? If its 93 then to save a few bucks every week you could, say you were almost empty you could ask for $25 of mid grade then $25 of premium so that you would be running 91octane which is perfectly fine for your truck.

 

I would stick with the premium gas. That's all i us.

 

Use premium. If you are that concerned about gas costs you should have NEVER bought the truck. It drinks gas like a fisherman drinks beer on a hot summer day

Look at it this way, say you are completly empty. You fill up with premium, which is only .10 more than midgrade. It costs you $2.60 more to get premium over midgrade. Fill up once a week that is about $150 a year. It is well worth it.

 

thanks for the info, not real concern, I was just wondering if what the dealer said was of any value about the gas.

not doing any mods to it except taking off the wing and putting a trunk lid on it. didnt want to attach wing to lid.

Otherwise its an awlsome truck....
