so how long am i expected to last w/ the mobil1 15k mile oil and k&n oil filter?

a whole year or actual 15k miles w/o needing to change filter and oil?

i changed about 3k miles ago

TheAsian

I would continue with regular oil change intervals. I havnt looked into this oil at all. Oil breaks down over to time due to heat, oxygen, and exhaust gases escaping into the oiling system creating a acidic solution.

On a brand new engine I'm sure you can go longer intervals between changes but I wouldn't use that oil and go 15k between a change.

depends on car, purpose, mileage of engine

gsr, dailydriven, occasionally smash around and mountain road driving!

im lazy and this is so much money saving if it actually works...

-40ish$ for a change + filter and oil
-dont need to change for a year including filters = savings of over 100ish$


all in all this is good for the lazy if mobil1 advertises it and it functions as 15k miles

teg_dc2

15k miles is a big interval oil change, idk if this is true or not but you can try if you want, as long as it's mostly daily driven and not raced all the time im sure it will be okay for 15k

racebum

would never try this on an integra. on a car designed for it, sure. 15k oil changes are common on say a cummins 5.9L diesel

not a big fan of mobil 1 at all because of their outlandish claims on their oil, the only oil i know for a fact that goes 15k is amsoil, and ive seen the test results on that. I use royal purple and i typically change that every 5000-7500 miles because i know its good for at least 10k, along with the purolater pure one filter. Given the test results.

i use mobile1 oil and their oil fliter. Expensive yes but had no problem with mobile1 at all. My car was daily driven and occasionally drag raced at the tracks. But i did change my oil every 3000 to 4000 miles. depending on how hard i was driving my car that month.

That's NOT what Mobil says. Mobil tells you not to exceed the change interval recommended by your car's manufacturer. That means 7500 miles or 6 months, whichever comes first, on older Integras, 7500 miles or 12 months on newer Integras.

If your engine fails, it will cost you a lot more than the cost of a few oil changes. Don't go 15,000 miles if you care about your car.

or....just use good oil and go 15,000 miles without worry, mobil 1 is a gen3 base dyno oil with additives, where as good "racing" oil like amsoil, royal purple, and redline, are gen4 and 5 synthetic bases.

racebum

close, you're thinking group 3,4,5 with the oils, not gen. the only safe way to do a long interval change would be to A: monitor your oil level and add as needed and B: send in a sample for oil analysis at 7,000 miles to see where you're at and if going longer could work. to even go this long you would want a pretty healthy motor. carbon penetration is a problem with higher mile engines since it begins polluting your oil.

Mercedes actually doesn't let you change your oil until the 18,000 mile mark. Also, they are using an oil that passes their very strict requirements. Look on the back of the bottle. If it says it passed Mercedes test then you can be assured it's worth it. That said, I'm not saying I would put this in a 100,000 mile Honda engine though and expect to let stay for 15,000 miles. I would stay with a good synthetic and follow factory recommended oil change intervals.

vtaker

Nah if its a gsr that's raced sometimes then i wouldn't go more than 6k. check the oil regularly too. 8k rpms is a lot for an engine so the oil needs to be awesome.

wtf_is_jdm

I find it odd as well that they make claims on the mileage one oil change can endure. Not all of us have the same road conditions, city/highway driving, or driver characteristics to make even across the board. I probably would not pay attention to it likewise. I still continue the 3 mo/3000 mile marker.

Drive 4 fun

As well as different driving habits, 4 cylinder vs 6 or 8. More rpms. I have seen tests that used V8s, as I recall, and tried some brands for high milage. Additives burn off and viscosity can change. Some would recommend oil change after track day with basically WOT and high rpm's for 1-2 hrs, in sessions.

racebum

you can normally fry oil in a hard track day. that's less than 100 miles. 300 degree oil temps and high sustained rpms are really hard on oil. redline is the best one i know of for track duty, often used in F1 cars it's a true group 5. the whole story on the mileage oil debate really comes down to the engine and how it's being used. a cummins diesel can go 15k+ if you are doing a lap day in the integra you should change it the next day.

I used to go 3 mo/3K on my GS-R with Valvoline 5w30 MaxLife synth blend. Recently switched to Mobil1 0w30 back around 275K miles and am now going 6 mo/6K on this oil. I've changed the oil 2 times in the past year. I can get a 5 qt. jug of it at WalMart for only $21.

When I was a kid, a very long time ago, my dad told me the single best thing I could do for my car was and oil change and filter every 1500 miles, he did it on all the cars he ever owned, religiously, he had very few problems with his cars/trucks.

I have followed his advice and do an oil and filter every 2500 klicks, [just over 1500 miles].

I may seem excessive, [the Acura service department thinks so] maybe even ****, but my 94 Integra that I have had as new and is a DD, I drag raced it for the first 2 years I had it and auto-crossed it most of the rest, with a 75 shot ZEX system it has 230k on it and it still runs like a dream, it does not burn a drop of oil.

I can only assume my good fortune with the car is due to the frequent oil changes, considering how hard the car has been driven.

BTW, the 89 Sunbird I had before the Integra had 489K on it, it also ran just fine and did not burn any oil when I traded it in on the Integra.

I am pretty sure I will continue to change oil and filter every 2500 klicks, the results speak for themselves. 94

it is excessive, very excessive, most oil doesnt even get dirty until about 2500 miles

It's all about the designs of the engines now days. The oil is made based on the needs of todays current engines, which demand more work out of the oil than old engines did. You should ALWAYS follow manufacturer recommendations for oil change intervals. They don't just guess on what they think is a good time to change, they spend a lot of time and money testing the oil and engines to determine when would be best. Oil these days have more detergents and additives in them so yes the potential oil life could be more than what is recommended for a 15 year old car, but in order to know that you would have to send a sample off to see how much of it has broken down, how much fuel and carbon is in it, etc.

fcm

So why even wait for it to start breaking down, I am guessing that there is no one here that will say that changing oil as often as I do is a bad thing, that it can in any way hurt the engine, lets call it "preventative maintenance"

Again, I have to go with more then 50 years of personal experience all my dads cars, [that I can remember] and the cars I have had, [and bikes] have benefited from the "excessive" oil changes, [high mileage without problems] and the cost, IMO is more then offset by the fact that no major work, [rebuilds] have had to be done to any of the cars I have had, [or may dads] except for the ones that were purchased used. 94

its called wasting money, good oil takes over 10,000 miles to begin to start breaking down. Even good dino oil doesnt break down even at its change interval of 3000 miles.

nsxtasy

Not true.

However, synthetic oil is more resistant to breakdown at high temperatures than conventional oil. (Which should have nothing to do with how often you change the oil.)

racebum

100 miles may have been an exaggeration but i still would have a hard time believing even the very best race oils like redline could survive 300deg oil temps and 6000-8500rpm long enough to have a 3k interval.

without oil analysis it is hard to guess just how many miles a car might make it in track conditions.

If your oil temps are 300 degrees you have a problem, most oil never exceeds the operating temp of the engine.
