Driven nearly 1M miles. Never had a fuel injector "service". Never had a fuel injector act up. One car covered 317K miles on its stock/factory injectors.About ready for my 100,000 mile tune-up....yes I drive alot...
Doing it at the dealer...will also do Fuel Injector service. Anything else recommended?
Complaints about NGK?? They make top of the line spark plugs. I use stock NGK's and change them every 40k (book says 30k) and have had no issues. They actually look like they could be run a lot longer. Nearing 154k now.Thanks A Guy...think il stick to the cirzt one mentioned. Due to how many complaints i have heard about NGK.
Not to sidetrack the thread, but those MPG numbers seem a little low. I have the MDS turned off on mine, and I’m pulling 18-19 mpg in city and 22-23 on highway (with cruise).Thanks A Guy...im still trippin over the fact of 16 plugs....but cant complain about my mpg with the 345 for sure..combined i get around 16 or so and on the highway with my cruise on 80 i get between 20 to 22 mpg
Now that i think about it, my rear-end may be passing my MPGs versus yours. I've got the 2.65 rear axle ratio gears, and I'm guessing yours are probably 3.06 or so at least. Not a huge difference, but enough to burn a little extra gas while rolling around for sure.Yes plugs are in and all coils were tested and are doing the right job as they should. Cant remember how i found my mpg on my evic now lol.. Not sure what else is needed for a tune up other than making sure plugs and coils are doing there proper job. Any idea how to find any maint records with my vin # or no??
The default spark timing of the engine is set for 89 octane gasoline, but through the magic of knock sensors, it can tell when less than 89 octane is being burned (or poor quality 89) and it will automatically retard the spark timing to accommodate. So no harm will come from running less than 89 octane, but since more (advanced) spark timing basically equals more performance, running 89 octane (or higher) will yield the best possible performance from the engine given its stock configuration (aka stock tune).Wow i did not receive a owners manual with the purchase of my 2012 challenger rt from glennbrook dodge in Fort Wayne In..sonce my purchase in march i have ran the 87 in it and just found out by looking at my pdf file of owners manual that 87 will work but 89 is recommended..so on my 2nd tank of 89 octane and seems to be a lil more smooth over all...however now my car seems to want to go by itself when its put in drive and yet my rpms at idle are between 600 and 700 it used to not do that at all...so wondering what to do about it?
