I'm curious to know when you guys are changing your oil. I've heard conflicting reports about how long Mobil 1 10W-30 is good for. 3K, 5K, 8K, 10K...whatever. So when are you guys changing your oil?

~THT

 

4k intervals.....10w-30 mobil1 supersyn.....i would do 8k changes but i drive my car REAL hard and do ALL CITY driving....if I did all highway then 8k would be on my list....

 

I am a user of the Mobil 1 filter only. I change my oil every month so I am using Castrol GTX 5W30.

 

I have mostly highway miles and I drive the car hard, so 5k oil intervals with blackstone analysis (which says I can push it farther)

 

Between 5k-6k miles w/ my synthetic

 

Same here, Mobil 5w-30. Lots of city/backroads, stop-n-go driving.

 

M1 10W30 with 6k miles between oil changes.

I just changed my oil 2 days ago..it was black..

 

since the filter has to be changed every 3500, i usually say "**** it, new oil while im at it too". 3500 miles is like every 3 months for me so i dont mind it.

 

Every 3750mi w/ the 15208-9e0000 filter

I do alot of hard city driving, then every 2 weeks or so I do some 250 mile high speed sprints between miami and orlando.

 

How many of you actually get your oil analyzed? Everybody has their own idea of how long you can run your oil. But only an analysis will tell you if the oil is still holding up.

 

5k here for my max. the oil test taken at 4500 gives good reading. I dunno if nissan filter is able to handle longer drain period.


~7k for my audi.

 

every single oil change is analyzed for me

 

10000 mile intervals and I change the filter every 5000. I put 500 miles a week on my car and still running sweet at 156000.

 

Next oil change, Im gonna do an analysis. Im sure that the oil can go much further than 3750mi, but nissan is quite adamant that I follow their routine if I intend to keep my stupid warranty.

 

Ditto.

 

using the same oil filter with new oil, its like taking a shower and putting the dirty underwear back on. i go 12,000kms before i change the oil. i change the filter with the oil change also.

 

Read it again.

We change the FILTER at 5k intervals. We change the OIL at 10k intervals.

There is never an old filter used with new oil.

 

 

Mobil 1 Synthetic 5-30w and filter change @ 5k miles.

 

5K with nissan filter

 

i change the oil at 3500-3750 with a new nissan oil filter. only use mobil 1 0-40w. mostly city driving.

 

My last oil change was 7k with an OEM filter... Normally its 3k

 

I change mine around 5000 mi, but according to Blackstone reports I'm pretty sure I could make it 8000 no problem, maybe more. I basically change it in the fall, so I don't have to freeze my butt off doing it later, and sometime in the spring because it's getting nice and sometimes once in the summer just because I can, or beat the heck out of it at the track and feel bad if I don't.

 

Every 6 months or 5000 miles, whichever comes first (usually 5K). Makes it easy to remember to change it.

 

We'll I'll probably do every 5-7k only cause it'll take me a year to put that many miles on.

 

5k or 6months mobile 1synthetic with mobil 1 oil filter.

 

I change my oil every 6 months (sometimes less if I am bored) regardless. I usually drive the car about 1500 miles a year, so I guess I change my oil about every 750 miles or so. I use Mobil 1 and the Toyota filter commonly used with the VE engine.

In my QX4, I change it every 3k miles, since my wife drives that thing all over.

 

5k with Nissan filter. Here is an anlysis I did after 4200 miles (was going on a long trip).

 

Do you drive very hard?

 

No, not often.

 

im at 7k right now and i was gonna change it at 6k but i just didnt have the time and hopefully i change the oil soon

 

where do you folks get a good deal on Mobil 5w-30?

 

Are you serious about this? How do you not get caught? What do you consider high speed?

 

Average speed for the Orlando to Miami sprint is 104.39mph.....there were some higher speeds and a few lower ones. I have a valentine one, that helps me stay out of trouble. I wont lie, I have been caught.

 

I haven't found a low cost source for Mobil 1; usually just buy it at Walmart by the case.

 

The cheapest Ive found it is at walmart and Advance autoparts, both were 24/case

 

Yeah, as soon as they got you with laser your screwed. You do it odd times with minimal traffic? I can't imagine making it if your all by yourself on the road. The laser will get ya.

 

Walmart. $19.82 for the 5-quart jug.

Laser doesnt have enough range on the open highway, they use Ka band. And if you know what you are doing, you can do it in mild traffic. Ask pedro, he has seen the way we drive
