if i change my oil then drive 3,000 miles in 3 days do i have to change it again?

Answer 1

While three months or 3000 miles is what is usually recommended for "severe use", that refers to stop and go type city driving!

If you drive 3000 miles in three days, you are obviously talking about highway driving. That is the easiest mileage on a vehicle. You can go a little longer between oil changes with that type of driving, so I would say that you do not need to get the oil changed right away!

Depending on the type of driving you are going to be doing after the 3000 mile trip, you can go to 5000 or even 7500 between oil changes! If you are going to be using the car for short trips or in stop and go traffic, you would want to get the oil changed at about 5000 miles and then go back to the every 3000 miles rule! If you only use the car for long highway trips (without severe traffic) you can go to 7500 miles.

This assumes that you check the oil level regularly, and add oil when needed!

Answer 2

The "Change your oil every 3,000 miles" isn't necessarily what your manufacturer would recommend. Every 5,000 miles seems to be the more realistic average, but read what they recommend for your make and model. That being said, yes, if you managed to drive 3,000 miles in 3 days, and it's recommended you change every 3,000 miles, you should change the oil.

But you'd be hard pressed to do 1,000 miles a day for 3 days. If you drove 8 hours a day at 125 MPH average, you could do 1,000 miles. Or 10 hours at 100, or 12 at 84. You'd have to average just over 62 if you drove for 16 hours, and that would be a grueling pace to do that for 3 days.

Answer 3

Only if your car has VERY high mileage and the rings are shot. This allows a LOT of contamination of the oil.

You change your oil because of contamination in the form of condensation, fuel, smoke from the blow-by blowing past the rings, etc.

If the engine is run for long periods like you said, most of the fuel and water is cycled into the EGR system and sucked back into the combustion chamber.

The blow-by smoke will continue to mess up the oil though.
Under your circumstances, you could add a couple thousand miles before changing it.

Answer 4

oil will last alot longer than the oil company's would like you to believe

the new porsche comes with moble 1 and has a 15000 drain interval

So in short the people here answering are just speculating on what they heard.

I would take the porsche engineers advice first i think they do their homework
and 5000 miles is fine

Answer 5

sensible man is wrong. starting and stopping the engine are much harder on your car then just driving it. a car that is only driven around town, for errands, etc, will be worse off at 20k miles than a car with over 100k miles that has been driven exclusively on the highway.... so to answer your question, it wouldn't be a bad idea, but you could let it go a little longer if you wanted. No harm done.

Answer 6

If you drove 3000 miles in 3 days hwy is nothing as if you look at the oil it's properly still clean> 3000 city than it done>And if your not pulling a trailer or extream conditions & load>

Answer 7

No oils two biggest enemies are moisture and fuel if you are running you car for prolonged periods of time fully warmed up then it is OK to run your mileage out most owners manuals will actually say 5k to 7k on the suggested interval.

those oils that are supposed to last or 15k are a joke if i ran oil that long in my car it would be half condensation and half fuel.

so 3k is not set in stone

Answer 8

Most oil changes are based on miles, not days. Your engine did just as much work in 3 days as it would have if you took a year to drive 3000 miles.

Answer 9

3000 miles or 3 months which ever comes first. switch to full synthetic oil and a high mileage oil filter and push it up to 6000 miles

Answer 10

If you drive a car long distances you do not have to change it that often . usually your manuals will tell you this.
