Maybe the reverse could be the answer to the US financial problems drive like the Greeks in the US as you would certainly get ticketed???Aha - I think you've stumbled onto the answer for Greece's debt problems ! Enforce the traffic laws with large fines and presto - no more defecit - at least that's the model being followed over here
I have a 2011 Sport with the same engine and the manual says 89 preferred, 87 okay. So unless they did something to the engine which I doubt I wonder where you guys are getting your manuals from.93 is preferred, that's right out of the manual... Even though it never said so in my 97 Dakota's manual, for the 3.9 it stopped the ping, and I picked up about 40-60 kms per tank! My wife's R/T is recommended to run on 93 as well...
Well premium in Chicago is $4.70, so when my monthly gas allowance exceeds the monthly payment I make on the truck I start to question putting in premium. My post was actually aimed at the person who stated that the manual recommended 93 when in truth it recommends 89 and you will do just fine with 87. Not like your voiding any warranties. It is all a personal preference. Similar to which gas brand is better. I buy costco cause it is the cheapest around here and it only comes in 87 or 93.Ok, so here is why I just run 93. If I put 89 Octane in it and lets say the gas is actually 88.4 Octane, then I have not gotten the full ability of the engine. Also most major companies offer a better blend of chemicals with the Premium Fuel. Anti Corrosion Etc.
I agree with you on what the manual says, but its just a few pennies more per gallon and I dont drive that much.
The current cost of gas in my town is 87-$3.85 89-$3.95 93-$4.05
I usually buy around 28 gallons per week so 89-$110.60 93-114.40
So thats $3.80 per fill up. As expensive as these trucks are I just cant understand all the BREW HAHA over the different Octanes. I drink more than $4.00 per day in Coca Colas
