i bought my truck new and it only has 5000 miles so i doubt cleaning the throttle body will help

 

What do you guys consider city driving? these people getting 14 or 15 in the city and still complain drive me nuts. I get 11 babying it and 10 in the winter. I get 17-18 on the hiway though which I'm not complaining about but I could always use more.

 

at first i read spark plugs every 10,000 miles, but then i read the rest. is this not complete over over kill kill?

also a lot of those filters actually work better with some dust/dirt on them as it catches more dirt from flowing in, a clean reusable filter will allow more particles in than when its been used a bit.

cleaning your throttle body every 1,500 miles???
F*** stp use marvel mystery oil every once in a while in the gas tank, also may want to pour some in the crank case.
Clean out the PCV valve.

if anybody else does what the guy with the "too large sig block" says and thinks it does something and/or is worth it please feel free to put in your $.02 or is it $.2 lol

BTW even chrylser (king of early maint) adv to change plugs every 30k miles.

 

i'm not sure what this guy is trying to prove but as ramitone said this is alot of everkill in my eyes, i'm not mechanic but owners manual says every 30000, plus who wants to change 16 plugs every 10000 miles? I'f i'm not mistaken K&N recomends you do a clean and reoil at 50000? so why would you go against what owners/operators manual tells you to do? I'm all for milage increase and i would love to know the secret to getting 15 mpg city, i only get 16.6 ona 300 mile road trip so please let me in on the secret, my truck has less than 6000 miles on it so i know the tb can't be that dirty plus i have cai and flowmaster exhaust.

 

bigbody - yeah I just cleaned my tb for the first time 31k, was pretty clean, put some cleaner through the PCV valve for the first time. Still need to check my plugs cause my mileage just dropped 2mpg, but yeah I can't imaging changing my plugs every 4 months. And with oil changes I really don't know why everyone doesn't use amsoil, I can see if they use mob1 but amsoil is still a better oil. Plus why change at 3k when its still clean at 7500? As for the diff, if it wasnt for the c clip issue I wouldnt change mine, I just put amsoil severe gear (100k mile) so I think what I'm gonna do is buy an oil pan just for that and wash the diff cover before cracking it and check the ring and pinion and then pump that oil back it. I may tap a new hole like when you change your oil so it'll touch less dirty metal when it pours out.

 

i've gotten as bad as 10mpg...and i have a 3.7 liter. wtfiswrongwithme

 

you dont know how to use the space button for starters lol

do you tow/haul anything (do you have OD engaged), go up a lot of hills? wait youre in cook county so no hills and its a rc 4x2. dont know what to tell you. you do have 4 gears right not just 3? lol......

 

it is almost impossible to tell
if an engine is 'healthy'
by looking at MPG
in city driving

do a "test run"
at a true 60 mph on a fairly level highway
on a day when the wind is not high

if your Ram is mostly stock (tires, lifts & light bars real MPG killers)
and the engine is healthy
you should get 20 MPG
measured gas pump to gas pump
on a trip of at least 100 miles

 

it may be over kill.....and no its not good to have dust on your *oiled* filter....thats what the damn oil is for.....I run the licing **** out of my truck thats why im always on top of ****.....my throttle body is filthy every 1500 miles when i change it....I can feel my truck losing horsepower if im not cleaning my air filter every 1500 miles.....as far as changing the spark plugs every 10,000 that was a typo i meant 30,000....

 

a dirty air filter did affect old fashioned carburetors

Despite what you may have read in newspapers
modern efi engines can tolerate highly restricted air filters
with no MPG loss

Marlan Davis, the technical advice editor of Hot Rod magazine
recently confirmed this about efi engines

Consumer Reports actually ran a test to confirm it
see below:

http://www.consumerreports.org/cro/c...-406/index.htm

sample quote:

According to our tests, driving with a dirty air filter in modern engines doesn't have a significant impact on fuel economy, as it did with older engines. While fuel economy didn't change, however, power output did. Both cars accelerated much more slowly with a dirty air cleaner. We drove both vehicles with their air cleaners restricted and found little difference in gas mileage with either engine. That's because modern engines use computers to precisely control the air/fuel ratio, depending on the amount of air coming in through the filter. Reducing airflow, therefore, caused the engines to automatically reduce the amount of fuel being used.
