Miles between oil changes

[ccjaco02]

I have around 5000 on my 05 DC. The semi-synthetic goes 5k between oil changes. I wont change it until 10000 and every 5k from there on out. Is it okay to change it every 5k or should the changes be done more often? The manual says every 5k is just fine...

Every 5k should be just fine. Unless you want to change it every 3k. Right now I'm running my Mobil 1 until 5k. Sometimes I change it at 3.....this time 5. Easier on the wallet....plus the oil still looks great after 4k on it!

David.. when did you switch to synthetic? mileage?

bottom line: the more oil changes the better!!!!! stick with 3 months/3000 miles. oil changes are "way" cheaper than engines. yspert

Go by the manual

In my younger, more uptight days, I'd change every 3k miles. Now I'm older and wiser and go 5k miles per oil change. Go 3k if it makes you feel better, but I challenge you to find just one person who had an engine failure because the oil was changed every 5k rather than 3k. I know I never heard of that happening.

I do the 3 months/3k miles thing, whichever comes first, but my daily commute to work is less than 5 miles @ 55 mph, which is not good for the engine, so I figure it should be changed more often... I usually end up with 2-3K miles in 3 months.

3 to 5k. It depends on driving conditions.
I rotate & balance and change the air filter at the same time.

This statement is bull hockey. For years experts have stated that the 3K rule was set up by the quick lube and oil industry. Yes, it is cleaner oil, but it is a waste of money. 5K is a good time to change oil.

Well I bought my truck used at exactly 24,000 miles and it was receiving regular oil changes by the Toyota dealer from the begining of it's life. The guy I bought it from was really nice, and really anal about the truck as well. As strange as he was, I knew that the truck had been taken care of, so that was nice.

I changed to Mobil 1 probably around 35,000 miles + or - a little bit. I just hit the 50,000 miles mark last night! Now sitting at 50,003 miles in my driveway . So far it has been great. Right now I am running a 5k interval on 5W-30. I am driving to Florida mid May (I'm in PA), so I figure I'll change the oil right before my trip since I'm at 4k now on it.

The oil really does look great after 4k! Of course it's a little dirty...that's expected, but not anything like regular oil. Just makes me feel better about the life of my truck I guess. It may not be worth it in the long run....but if it is I'll be glad that I did it.

Quick question.....still on the topic of oil. I've heard that synethic oil isn't good in the rear diffs of 00's and 01 Tundras. Anybody second that? I need to change it soon as I'll hopefully be installing a Powertrax No-slip

I am doing my oil changes every 5,000 miles. I just took mine in for an oil change today as a matter of fact.

If you're using Mobil 1 synthetic and changing your oil every 5k you are throwing your money down the drain. That oil was designed to go much farther than that. The company that I work for has oil change intervals of 80,000 miles with no problems.

Keep in mind, if your "engine" is still under the "FACTORY 5/60K" warranty....
I would consider staying within 5K intervals as recommended in your owners manual. Just a thought.....

This is one site of many. Do a research on google and type "3000 oil change myth". There will be many sites that come up. I am on the job site and there was one that I wanted to get to but the company filter knocked me out of it. I want to say something here also, I was not trying to dis or put an ugly spin on your comment. I am one that thought Motorcraft and Quaker State oil was good oil years back and found out through Popular Mechanics in the late 90s that it was not quality oil. If you ever get your oil tested, you will find that it is not needed UNLESS you live in a dirty environment or you live in a stop and go area.
