YACT: longest oil change interval your car has gone through

[LAUST]

my first DP 🙁

 

[zCypher]

I was betweeing 6000-7000 kilometers on my Lancer before its very first oil change, and they told me to come back at 12000km to change the oil again and general checkup i think. Something IS weird though... lets say I push the car pretty hard - up to the redline through at least gears 1, 2 and 3, brake hard etc. Let's say you do this for maybe 15 min, but never holding it at redline or JOLTING the car or doing anything real sudden - still going real smooth and everything. Should this be considered really bad for a car, or a new car for that matter (that's already broken in)? Cause i've heard a strange noise ever since i got it, and it only happens after I go wimming like that... then if I shut off the car, put gas in, and start again - it doesn't do the noise anymore.

heh

10,000+ on the old Benz Wagon, manual states every 7500 or 10000 on dino oil.

It's all "dino" oil, all made at the same refineries with the same basic feedstock; unless you are talking about vegatable oil.

Oil can last a long time if it isn't contaminated with spent fuel from the engines combustion cycle. That and moisture are the primary components for lubricant failure.

If you really want to know the exact interval to change your oil, get a sample tested every week for moisture, acidity, etc.. 3000 miles is a very conservative interval that works well for engines far beyond their prime.

Uh..?

It's not dino oil if it's synthetic.

I agree with the rest of your statements though. 🙂

All I'm saying is that synthetic oil is created from the very same crude oil that "dino" oil is refined from. It's just a tailored molecular chain versus naturally occurring chains from the refining process.

A year/22000 miles, on regular oil.

 

[BatmanNate]

3500, plain old 10w30 dino oil. (3500 is Toyota's spec for the car)

 

[Dacalo]

I change oil religiously every 3000 miles

 

[Yzzim]

I went 4,000 miles between my oil changes and just about freaked!

Never went over 3000 on the Shelby, not that I beat on it, I just like fresh oil lubricating my turbo 🙂

You mean the Plymouth Duster 😉 ?

Real nice. I'm sure you told the guy you were selling it to that it got regular oil changes every 5000 on the dime, too.

Real nice. I'm sure you told the guy who's post you are responding to, that you always jump to conclusions, too.

3100 miles since I got it.

10,000 miles on my dad's 98 Audi A6 with Mobil 1 10w-30 and Mann/Mahle oem filter. Oil analysis came out fine. Gonna switch to German Castrol Syntec 0w-30 after.

5,000+ miles on the hondas, with either purolator, stp, or supertech filter, and using either 5w-30 or 10w-30 Mobil 1 depending on what season it is. Havven't done analysis yet, but will on next change.

I wish I could afford amsoil. It is excelent oil, but not that locally availible. The extra drain intervals make it worth its price.

If you really want to know how long you can/could let the drain interval go, get an oil analysis done and read up at Bobistheoilguy.

12k on my old Kia Sephia. Full synthetic, not exactly a performance car. I could've gone longer (the oil looked brand new) but after 12 months, it just seemed wrong to wait longer.

 

[isaacmacdonald]

around 20k miles in my 87 cutlass cierra. Mind you at that point (stopped changing the oil at 300,000 miles) the thing burned a case of oil every 40 days so I just ran the thing until the transmission died.

 

[huesmann]

You can prolly go way past the 3000 "recommended" (more like scammed by oil companies), but you do need to make sure you top off with new oil and don't let the oil level get low. Sure there will be impurities in the oil, but adding more will keep your volume up.

10k on my old motor but only because I knew it was coming out anyway. On my new one I haven't decided yet. Prolly about 5-6k on Mobile1 with a STP filter. Thinking of switching to Honda OEM tho.

I had a '70 Dodge Dart with a slant 6, bought for $400 with 118,000 miles. Sold it a year later with 132,000 miles, only added oil the whole time (used a quart every 200 miles or so!).

Some oem honda oil filters aren't too great. STP is better IMO.

 

[mattgyver]

I once went over 20k in my truck. My dad says he went about 50k one time with no ill effects.

 

[Argo]

10,000 miles.

 

[luvya]

After reading this thread, I think I will change it every 5000 miles instead of 3000 miles...Thanks guys 😕
