Why you change your oil

[joe603]

Just a quick reminder that despite what anyone might say about oil longevity, you need to change oil regularly!

Really nasty BMW!

WOW...

I actually called my gf over to show her the harmful effects of going over between oil changes. Last time she only went 4K km over, but in her Sunfire she had gone 10K km over once without telling me.

Then she wonders why she's not allowed to drive my car.

I bet the only reason it lasted that long was because of its 8 quart capacity. A QX56 has a 7 quart capacity. Thats a 339 cubic inch big block V8. I saw one go 24,000 miles, ORIGINAL OIL. It died at 27,000.

WOW.

know a guy who thought that oil changes were a hoax so that we would spend more money to pad the oil industry's pockets...until his car died from having ONLY sludge in it.

In relating oil changes to people, I see it like brushing your teeth. The guy who never brushes his teeth, probably has none in a few months. The ones who do it frequently, have no oral ailments.

I learned that lesson in the early 1960's with my 55 Chevy six cylinder 3 speed stick. Paid $300 for it and shortly after I bought it I noticed it was leaking oil around the oil pan.I dropped the pan and the mound of brown/black sludge looked exactly like the photo on the first page of the bimmer post.

I cleaned it out, took off the valve cover and cleaned that out & had no more problems with it except for a new clutch. The first & only time I installed a new clutch. I can still remember the weight of the transmission on my stomach while laying on my back.

Anyway I've been changing oil every 3000 to 4000 miles ever since.No expensive oils. Just 5w30 what ever is on sale.

Anyone who changes their oil EVERY month needs their friggin head examined! At 500 miles a month ALL HIGHWAY you could easily go a YEAR between changes especially w/ a M1 synthetic.

he might just be ballin like that... i love the way my car feels with fresh oil...

but im like telcoman... every 3k to 4k... longest i've went was 5k... but i use synthetci oil...

I just like how the car responds with fresh oil + have you every seen how Black the oil is After 500mi it like moring Coffee. It look like i'm over due for an oil change. NO oil change for Once a year with Syntec, Sure if i lease the dam thing I would care.

I Manage 3 Gas Stations in MA All with Shops. I can say I have seen some f*** up things that People would do to there car.A guy come in with a porsche for a oil change it recomends Syntec but he wants Regular Bulk oil.Why buy the car if your going to kill it in the long Run. You are oil reguired to 1 oil change a Year on those car and it cost $700. The Dear Has tilted Lifts to Drain the oil Completly. Don't be Cheap the oil is the blood of the car. Take care of your investment Guys.

There's a huge difference between "cheap" and "wasteful".When I buy bananas at the store they're green, and they turn yellow and then a little brown, but overall their just fine. Same with the 3 day old steaks I buy at the store. Most people think the nice bright red steaks are the best but after a few days, after the meat has cured and rested, it turns a little brown and becomes a much more tender, better tasting steak.

I can't speak to your coffee brown oil. But I change the oil in my CBR1000rr about every 2k miles for many reasons (high compression, wet clutch gearing sheer forces, tight tolerances, high RPMs and high heat) and it's never "black" it still has a nice "oil" color to it. The 7,000 mile OCI on my old Honda did produce some pretty black oil...but that engine ran for over 220,000 miles before I sold it and it had no problems at all. My Chevy S-10 had about 175k miles if I remember and I used the same GTX castrol on that as I did the Honda. Both ran for a long time, both were in great shape.

500 miles per oil change is a total waste. You may even be doing more harm than good. Check out the BITOG site and there are recent studies coming out that used oil, in the 2,000-3,000 mile range, actually provides a better protection than brand new oil after it has broken in a bit. Just like a brand new engine versus one that's properly seasoned and broken in.

Maybe I'm crazy, maybe you're crazy, but I've never "felt" any difference in any car or motorcycle or boat that I've owned and worked on after an oil change. Maybe if you're going from a 60wt oil to a 0wt oil the engine might spool up a little easier. Maybe you're a robot or sometihng and can feel that imperceptible difference. I pay pretty close attention to every vehicle and every car and every bike or boat I've ever worked on or owned and I can say with pretty much certainty that i've never "felt" a difference between oil changes. A 500 mile OCI is a complete and total waste of time money and resources.....IMO of course!
