I've heard some say they change their oil every 3,000 miles others say 5,000. What do y'all think?

5,000 is what I do.

ShunDoe

Is that with any car or just your Lexus?

Depends on if the car has an oil-life monitor. Absent a monitor, 6 months/5000 miles is a generally good interval.....maybe 3/3000 if the driving style is very hard on oil.

Every car is different and has different needs. So follow what your owners manual states. It's as simple as that. The factory did all the research for you and knows what is best for your exact engine. Trying to follow another regime is crazy or a waste of dollars.

Depends on what the manual states. On my 2013 ES, it's every year, or 10k miles.

On my 2nd BMW in a row, and I don't drive like a maniac most of the time, so the OBC calls for an oil change every 18,000 miles or so. I'm actually a couple hundred over, planning on doing it this weekend.

The RX350 is a larger engine with a smaller oil pan, so it gets changed every 7,500 miles. Had been planning to push it farther (shooting for 15k, supported by UOI) since the oil I use is rated for 25k miles, but since I got a vacuum extractor, it's just so damn easy I'm not going to bother. Don't even have to get out the jack.

7500 to 10,000 is what I do. Just make sure you check the dipstick every now and then to ensure you are not getting low. If there is a fear, then 5000 is good.

What oil do you use?

ShunDoe

What oil do you use to be going 25k miles ?

ShunDoe

I change my oil every 3,000 miles, reason being is because that is around the mileage that the oil start to get dark.

Performing periodic UOA (used oil analysis, preferably with TBN) on samples of drained oil will let you scientifically determine the optimal oil change interval for your specific engine, driving conditions, and oil. If you don't want to go through the cost and hassle of that, following the manufacturers recommendations is probably the most sensible approach.

Amsoil Signature 5w30. And to be clear, I don't currently use it at an OCI of 25k, but it's rated for that (or one year). I use their European Formula in the bimmer.

Whatever synthetic oil the Lexus dealer uses.

For both my RX and GS, I just follow the manufacturer's guideline of 12 months/10k miles.
