YACT: How long can a car last with no oil change?

[Lebeau]

Not related to the original topic but do you use 5W20 or 5W30 oil for your Accord?

its 99, before the 5w20 era.. so im using regular 5w30

 

[Lebeau]

I have a 99 accord and it uses mobil1 and i dont care what people say, it gets new Mobil 1 every 3k or max 3500 if it rains on a weekend..

I hope that engine seizes and they buy a new one for 1000 and not invest 6 dollar for 4 qt or oil or 10 bucks for how any qt that car needs

Synthetic is good for 5K miles, you're just pissing your money away. And your post makes zero sense.[/quote]


It may, if you can prove it, hope you got some oil analysis to back it up. Because I do, just sending two bottles to blackstone lab for my 100k+ analysis

and I'm talking about when it rains on weekend, i can't change my oil so I have to go a extra week w/o oil change at 3500 mile not rain affects my change interval

I think you'd have a hard time proving that synthetic was quantifiably better than regular oil, much less the difference between synthetic @3500 and @5000.

Fact is, 3000 is overkill for a regular car in regular conditions, and since syn is known to be even more resiliant than conventional, you are literally throwing money down the drain, or at least into your oil drain pan every time you change it And I base that not just on anecodtal evidence, but also having seen plenty of charts and crap from people who have done more involved testing and sending their oil off to get analyzed as well!

dawhimSurely that guy had to top his oil up...? 65k is pretty good on one chang even if the car is all but dead now!

My friend bought a Ford Bronco that had gone 13 years without an oil change and still ran.

Actually the lab analysis is pretty thorough, they can check how much of the additives have been "used up" so it can tell you if you're changing the oil too soon, too late or about right.

That almost makes me angry just reading that. How can people be so stupid?

I can't even contemplate spending all that money on a piece of machinery and then not even spending the time to keep it working like a well oiled machine..

Hmm.. That's almost interesting.. It's like people don't look at cars like machines or something, they're just.. there, to be used.

Come on man, no need to get upset. It's their dumb selves with their own dumb money. If they have money to play and blow up cars every now and then no big deal really.

I'm kind of glad i have a very common car. If I ever blow up my engine, it's just like 1k for another powertrain.

I don't the issue is as much "will the car run" as is "will the car survive another five miles?"

If it is the 2.7 engine, it could be the timing chain ready to go. There is no telling what other damage could have resulted. He could always take the top part of the engine apart and look in the timing chamber to see for himself. Not the smartest thing to do on an engine that is already prone to sludge, if it is the 2.7 L.

Have any large scientifically approached studies been done about oil change intervals? I know that consumer reports did one and they recommended a 6k interval as being perfectly fine (and this was on taxis, which are all city driving and idle all the time). Any others?

 

[ScottFern]

stupid people.......

 

[Lebeau]

So its true about ATOT people.. you do the right thing for your car, people tells you, its a waste of money, you do the wrong thing people start calling you names... i like for you guys to tell the Enzo people that they dont need to use helix oil, since to you guys it might be a waste of money

enjoy your extended oil change interval, you might as well be running amsoil for their 25,000 mile change interval

It's no skin off the back of anybody here if you keep spending more money on oil than you have to. Obviously you pulled the 3000 number out of your rear. Why not change your oil every 1000 miles? Why not every 50 miles? It's better for your car. In fact, you should set up a tank in your trunk with an oil dispensary that ensures you're never using the same bit of oil twice. That way you could even save money and not bother with an oil filter. But again, nobody here really cares, since it's your money, not ours. If instead of taking advice with an open mind you're going to be defensive about it, go ahead and do what you like

actually, his father believes it is not needed to have oil change.

1. His father is a dumbass with a capital D.
2. If he changes it now, it's all over for that engine. Just keep it full of oil, drive it until it quits, then shoot it.
3. Did I mention his father is a dumbass?
4. I have personally seen and worked on quite a few cars that came in with 40k+ miles with the original oil and filter still in place. We generally recommended that the oil not be changed at that point. On the ones that the customer said do it anyway, every one was more noise when restarted, and expired soon after. I remember one F150 with 55k that had the original factory filter, and when the drain plug was removed, nothing would come out. Sludge showed full on the dipstick.
This was back when Ford had 6yr/60k warranty, and the guy was pissed when the factory rep refused to warranty the engine.
5. BTW, your friend, AND his father are dumbasses.
6. Last summer, a customer brought his 2002 Ranger in for service and a couple of minor warranty items. One of them was a ticking noise. The tech came up front wanting to know when the last time the oil was changed because it looked really thick when draining out. We looked it up and we had last changed it at just under 5k. The truck had 28k during this visit. After the customer finished swearing up and down that they had changed the oil at Jiffy Lube (no dice, it still had the Motorcraft filter we put on), they had receipts, etc...they told us to go ahead and changed it, against our advice.
We did, and by the time the tech pulled it around front, it was knock, knock, knocking in heaven's door, if you know what I mean.
Customer was pissed, saying it wasn't that noisey before we changed the oil. Yep, that's why we told you not to change it. No warranty.

why do you recomend it not be changed at this point? What does changing do to the engine vs not changing it?

 

[no0b]

Same reason why not to change the ATF after 90000 miles, there is a sludge build up and the change of the oil can cause the sludge to move around the engine and cause havok with other parts.

lmao

this thread cracks me up!

You could probably do a Google search.... I'm not sure myself. Lambo's use that oil too and are only supposed to go something crazy like 500 miles between changes, an $800 change at that! On top of insurance for those things, where you call the insurance company on the day you want to ride, I don't know how people afford those things!

 

[NeoPTLD]

I wonder if my car needs oil change at all if I ocassionally change the filter.... It eats about a quart every 1500 miles. If I keep adding one quart every 1500, it's constantly being replaced little by little.

GM Claims with their GMOLs, you can extend oil as much as 12k which is pretty cool

The GMOLS will automatically adjust the oil change interval based on engine characteristics, driving habits and the climate in which the vehicle is operated. For instance, mild highway driving in a warm climate will maximize the interval between oil changes. Depending on the vehicle, this could be in excess of 7,000 miles and as high as 12,000 miles (in some models). On the other hand, short trip driving in a cold climate may limit the oil change to 3,000 miles or less. In general, most people that drive a combination of city and highway find that the GMOLS will indicate an oil change every 5,000 to 6,000 miles. GM data shows the OLS extends oil change intervals without risks to the engine.
