Hi Guys...

For argument sake...this is "ONLY" on dino. oil 5/20-30 etc (SJ)

Do you change according to elapsed time...i.e. 90 days etc.

OR

Do you change according to how many miles since last change?

Difference being...towing/city..stop & go/hi-way/time of year..etc.

Thanks for any input. Good luck...OT

 

I change every 5,000 km (3,000 miles) regardless of the time in between changes.

 

I change at 4,000 miles dino or synthetic.

 

HI!... I change my engine oil every 2500 - 3000KMS no matter what. I do a tranny fluid change/filter once a year no matter what and the same goes for rear end fluid.

 

I change mine every 3-4,000 miles...Synthetic or Dino oil does not matter.

 

I do mine from 3000 to 5000 miles at how ever long it takes to get there 3000 miles most of the time and 5000 when I'm on my long road trips or vacations.

 

2500 to 3000mi. I will do it sooner if it's more than 90 days. I will get fresh oil before and after a long trip. I will have to follow NEAL's example on the other fliuds!

Every 3000 miles. No exceptions.

I changed my oil today at 3000 miles.

 

once a year. Filter every 6 months.

I change every 5000 or 3 months, whichever is first.
Reason being that conventional oil is as good as synthetic for the first 5000 miles but conventional oil absorbs moisture, fuel and other contaminants easier which is why the 3 month rule.
My wifes Altima owners manual calls for 7500 mile intervals but since she drives only 6000 miles a year, I have that car on the 3 month plan.
Changing synthetic oil every 3000 miles would be a waste of money.

 

I am changing every 3000 miles and am using Valvoline 5W-20.

 

My dealer has set the oil change interval at 5,000 miles or 6 months. It usually ends up being every 6 months.

 

For regular back and forth to work, I change mine between 5k-6k miles (Mobil 1 synthetic). When I used dino I would change the oil every 3k miles. I switched to synthetic because I drive around 600 (mostly open road) miles a week and changing the oil every 4 to 5 weeks gets old and pretty fast (especially when you haven't taken the oil from the last two changes to be recylced).

If my driving conditions are more servere than regular (like in the summer when I'm pulling the PWCs around every weekend), I drop the change interval down to 3k-4k even with the synthetic oil.
