Motor Oil

[Pete]

I bet it will feel very wierd to resist the change the first few times

Yea, but I have known my share of women who ignore oil changes totally synthetic or not.

If the Jeep has has ANY conventional oil in it then you are doomed to that and that only. Going from Conventional to syn. will break down most of your seals mush faster.

BUT if the previous owner used Full Syn. (stock for any DCX vehicle) then keep on using it. I Use full syn. and change it out every 5-7k with no issues. Its an 04' with 53k on the dial

EDIT: Oh yea, my car uses 5W-30 Mobil 1.

ive always heard going from synthetic to dino will screw your junk up. not the other way around.

 

[dustin]

And shouldnt synthetic oil get dirty just as quick as dino oil?

Not me, I'm all when it says it's time for an oil change!

It is not so much dirty as it is breaking down and losing its lubricating capability. Synthetic does not break down nearly as fast as conventional oil. A good filter will take out the "dirt". You should not use synthetic in a brand new engine until the rings seat because it is too slippery and lubricates too well.

Good girl Even conventional oil has come a long way in the last 10 years. In the old days it was 3,000 miles, now most manufacturers are up to 5 or 6,000.

Beg to differ... In the old days it was 5000 to 7000 miles (long before snythetics). In the last 5 years, manufacturers recommendations have been 3000 miles. Me thinks change often, spend more!

Oh yeah I'm with ya on the chemical properties..etc... and the break-in...

I just don't understand why two identical engines, with same oil filters...all run the same way...etc. etc... and the synthetic wont get dirty as fast as dino??? (dirty as in darker..change of color)

It also depends on how you drive as well (you know schedule A and B?)

But I wonder if there is any truth in the manufacturers creating closer engine tolerences in an effort to increase HP while maintaining/increasing fuel economy has had anything to do with the increase in frequency of recommended oil changes?

When I gotz my drivers card 15 years ago it was 3,000 if you did alot of city driving and 5,000 for long highway driving.

You sure it is dirt or damage to the oil from heat.

"dino" being organic, is susceptible by nature to natural crud. synthetics however, have yet to find their trashbag!

I have no clue.

Guess that was bad example.

But doesnt some dust/dirt get through the air filter and enter the engine and containmenate the oil over time?

The vehicle manufacturer specifies which grade of oil should be used for the vehicles it produces. The manufacturer also specifies how often the oil changes should be made. For example, most people in the United States believe that a common oil change frequency should be every 3000 miles or every 3 months, whichever comes sooner. This 3000 mile oil change interval has been relentlessly promoted by oil changing companies for decades. It had a scientific basis when engines used non-multi-weight, non-detergent oil. It no longer has any scientific basis, but it is still being promoted by certain entities, most notably the oil change industry in the United States (including car dealerships). Indeed, studies have shown more wear occurs with fresher (1000-2000 mile) oil. This is attributed to additives re-establishing themselves, TBN converging, and filters becoming more efficient. Most manufacturers recommend oil change intervals of 6,000 miles or more for modern cars.

wikipedia is indeed a superhero!

Shoot my Civic manual says change the oil and filter every 10k miles (i do all highway driving) but I wouldnt DARE do that.

I just go to about 5-6k...

Oh well...

So Pete do you run synthetic in the bike?

 

[MJ]

Can I hang out here in the boy thread? The girls are really angry and mean tonight!

I use synthetic and I have a K&N air filter.

I run synthetic in everything. On the new bike I used conventional oil the first 1200 miles during the break in period. Now I have HD synthetic which is crap but they didn't have AMSOIL. I use AMSoil in the truck, and the truck before that. I go 2 cycles on the GM oil monitoring system, about 10K or so. On the bike I can tell a big difference, runs cooler, more zip.

AMSoil has even longer oil change intervals and they guarantee it.

I got 43.28 mpg on the Ultra classic today loaded up. Not bad.

a panel filter, FIPK, or CAI?

 

[Kyle]

Pete.

3000 miles is ridiculously low in any modern vehicle.

Currently both of my F-150s specify 5w-20 and 5000 miles. My 92 used to be 7500 on Schedule A, which was 90% of the use it saw.

wow 43 on that bike is pretty impressive! did you even honk on it at all?
