around 5k

 

hmm i would say 3-5k

 

I hope most people know this already but it depends on ur driving too. A lot of city = more oil changes. Mostly freeway (like me) = less oil changes. But its always important to check the color and smell of the oil to determine the status of the oil.

 

I go 5-6.5k, I check my oil in between that and if it's low or dark and smelly I change it if not I wait 6.5k and do it when my sticker says lol

 

Colour and smell are not great indicators (unless something's really horribly wrong), only a used oil analysis will tell you for sure. I run mine 10,000 km (about 6200 miles) between drain and fills, with a filter change halfway. I have not done any UOA, but I suspect it's good to go for longer than that. Coming up on a change tomorrow, in fact.

EDIT: BTW, just judging by the title, when I clicked I was sure this was going to be a thread about fapping...

 

I think there is a thread about that. I did this way to get people in to read.

 

This might be true, but keep in mind that most synthetic oils are rated at 7500 miles tops, anything over, and you can't be sure your motor is still well lubricated and protected. Beyond this, oil filters rarely work that well for that many miles. Even if it does hold together well enough for that many miles, it probably stopped working effectively a long time ago.

Yes. Keep in mind that oil still needs to be broken in. Changing synthetic at 3k miles is changing it out just as it's being worn in and becoming effective and can actually be more damaging to your motor. I would ideally change synthetic every 5k, but be careful about your oil filter selection as some of them aren't guaranteed to make it past 4k.

 

Send a sample in its only 25 bucks 35 with TBN test. Also any decent filter will easily go 10,000 miles no need to change halfway.

and Bingo! Oil is designed to suspend dirt and metal particles so who cares if it turns dark, also if you do short trips and do not let your engine warm up to proper temp that might get fuel in your oil, if you let your engine get to operating temp you should not have any issues with fuel in your oil. Unless something is wrong of course




I go 5k on Castrol Syntec, which I have tested to run, I could go for longer.

 

Any oil that is rated for miles is hogwash...Also as its proven time and time again just because an oil says you can go 15k or "x" miles has no bearing if you can actually do it. Its all just BS marketing.

Oil filters rarely work beyond 7500 miles? Where did you get that information? Virtually any decent filter, Purolator, Wix, Bosch, K&N, M1 can go 10k miles.

Some aren't guaranteed to make it past 4k? which ones dont?

Also there is no such thing as "Oil being worn in" this is the funniest line in your post

 

Well since i had my G i been changing it out every 5k and i always take it to the dealers b/c i am lazy to do it myself.

 

what he said

 

I actually did not change halfway this time, using a Wix 51356 (Maxima-size) filter so am probably okay. SS - have you ever done a UOA after running 10K miles and on the same filter? Not saying you shouldn't, just wondering what the results were.

 

Nah never ran that high, I always change my filter when I change my oil, Sure I could possibly keep the filter for two OCI's but I get them with the oil specials so I change them out, There is a guy who ran for 9k miles on Edge with the M1- 110 Filter(m45 filter). And as you see the insolubles % is fine.

For a 6k OCI changing filters half way is way overkill imo. Even with the normal VQ sized filter. You are more than OK with your Currently installed Wix

 

3k full synthetic

 

every 3k miles full synthetic plus a free car wash x]
