3,000 or 7,500

Posted

Manufacturer recommends oil to be changed at the 7,500 mile interval along with other things. I've heard of people going to the full 7,500 and some won't even go past 3,000.I know it's a dumb question to be asking but, I can only come up with 2 conclusions to this.3,000 miles can be pretty costly but, increases engine life as it's being flushed out with new oil. I guess those who can afford will do this.7,500 will be more cost effective in the long run but, you have just doubled the contaminants introduced into the system by doing it at this time. We all know that oil serves us 4 purposes, and that is, seal, cool, lubricate, and clean. Only makes sense that all four of these lack in their respective department by extending the interval.What do you guy's think?

7500 miles for me. my 91 honda accord also has a 7500 mile interval also. 3000 mile oil change is a myth created by oil companies. most vehicles i have driven actually had a 5000 mile scheduled intervals, or higher :2cents:

I change oil every 10K miles... But I've got a Frantz filter... The owners manual calls for 7,500 miles... You could have my Honda ATV 2008 in the owners manual requires oil change at 600 miles... :duh:

  • Owner

what kind of oil are you running Mike and what is a frantz filter???

Chevron Delo 15W-40...

Toilet paper bypass filter that filter down to 1/2 Micron.

    I did that for the first 500k miles. That's true.

    But look this man has managed to drive his 01 Cummins to the 900K milestone and still got room to spare... Now heading down the home stretch...

    Not a mile less than 7500. I Worked at a shop that serviced a fleet of dodge 24 valve cummins when I left the high milage one was at 800k lowest mileage one was 400k and they did conoco 15w40 oil and always had 10-12k on the oil changes with just a baldwin full flow filter. These were over the road rigs that pulled 40-45 foot enclosed gooseneck trailers that were loaded heavy, every rig had airbags inflated very hard.

    Ok... So just for the other people that visit the site what would you guys consider a safe upper mileage limit for oil changes? This of course is using a using a good quality lubricant (petroluem based) and a quality filter like fleetguard, baldwin, etc... I know changing every 3K miles is a waste for sure... :duh:

    Based on CAJ and W&F = 10k ..... good enough for me !!! :thumb1:

    With stock injectors 5000 to 7000.With big injectors washing down cylinders 3000 to 5000.Sorry i still go from 3000 to 4000 max.I just have a hard time trusting it over 4000.Maybe i should get blackstone to test it at 4k?

    My 8k to 10k are mostly highway and that means an oil change every week and a half or two weeks. I dropped down from 20k because I got scared. WHen I head the head off at 600k the cylinders had all the crosshatching. I use delo and fleetgaurd stratopores. I dont use the non stratopore ones.

    so me changing my oil and filter at 3k is a waste of time and money!:shrug: i dunno i think i agree with Dually it has been engrained in my mind for my entire life that 3k is time for fresh oil.

    I go 12000 km which is 7500 miles. I wouldn't be afraid of more. I did some oil samples on our tractor and at 450 hours the oil was testing perfect. The recommended interval is 250 so I think anything less than manufacturers specs is overkill.

    If I err not that's what it is. I'm sure my owners manual says 12000 km. I'd go out and look but it's cold, windy, and snowing right now:rolleyes:
