its not old or outdated at all. if your using straight up dino oil, its a very valid rule. if your using a blend/full synthetic then that rule starts to show its fallacies.
lol ok Devon white flag is out. I wish I could get my hands on the report, I think you would find it an interesting read.

I guess I should say, given the conditions. Here is an oua of cheveron 5w 30 dino oil going 6k + miles, with still some life left in the oil.

lol my car has 20k on it.
I change the mobile 1 synthetic every 2.5k, and wash the K&N every oil change...
it got amazing mpg's before i did **** to it.
I checked the plugs and they're mint and gapped correctly. Got a new fuel filter 5k ago.
only think in the car is my *** and my bat. yes ghetto.

Is that a production run of oil or just a sample run? Thats a great report! IIRC all our dino oil test patches took a crap around 5500 miles.. complete sludge by then.

I get around 17 MPG mostly in town, but I usually apply the skinny pedal a little heavy. As others said maybe the canned tune is not too good, I have nothing but good things about the Bama tuning from AM.

Help!!
Is that just a tune up? Or is there more to a tune up? I am low on funds and I have no idea how much a tune up costs. My mileage counter doesn't work, I was having over-heating problems so my dad changed the needle, now the needle doesn't work right. It barely makes it to the first normal line sometimes. I need a lot of help

There are numerous characteristics of synthetic oil that make it a superior engine lubricant--but it load's up with contaninants (acids, solid by=products of combustion, and other bad stuff) at the same rate as dino juice.
I run 10W-30 Penzoil (or Q, same thing) from Wally-World--they have the Motorcraft 820S filter for $3 or so too--and change it every 2500 to 3000 miles.
My grandfather told me 50 years ago that oil was cheaper than engines...

Re: Oil Analysis, unless you are just trying to see how long you can run it I don't see the point--the analysis costs as much as 6 qts, of decent oil and a filter...
