Rust in oil

I recently bought into the tacoma world with an 07 trd sport from a used car dealership. When i got it home I decided to change the oil and when draining it there was a decent amount of what seems like rust flakes in it. I went over it with a magnet and nothing was sticking so I’m pretty sure it’s just rust from sitting at the dealership. I want to know if it’s something I should be concerned about though.

 

Thats not rust, that's sludge / burned oil from lack of maintenance. If you cut the oil filter open, You'll find a lot more. Keep a very close eye on oil consumption...That is not a sign of a healthy, well taken care of engine.

 

Welcome to TW
Did you replace the oil filter too, needs to be done if not. Reinspect on your next oil change, maybe 3000 miles just to be safe, and to flush out anything else that didn’t come out the first time, and hopefully everything starts to look better during your subsequent oil changes.

 

More that the last owner(s) did very often.

I'd change it and the filter again in about 500 miles

 

UOA time.

 

Thanks for the info, it seemed like previous owners didn’t take great care. How concerned should I be about it?

 

Put a quart of Marvel Mystery Oil in on your next change. I use it at every oil change preventatively. It will help clean up sludge and prevent corrosion. I’ve been using it for years and am a firm believer, especially on older engines.

 

Thanks, I’m happy to be here. And yeah I changed the filter too. Ill definitely be changing it again soon

 

Yeah it seems that way

 

UOA?

 

Awesome I’ll look into that, thanks for the info

Welcome to TW! Hope your next oil change is soon, and looks a lot better.

 

Or, why not request a Blackstone test kit and send off a sample?

Ahhh ok I’ll have to check that out. And thanks! It definitely will be.

 

I’ll for sure send one with my next change.

 

You did good changing the oil,you should also change all the other fluids,transmission,rear-end transfer case,brake,power steering,etc

 

Probably a good idea, based on the oil previous owners definitely weren’t

 

How many miles?

 

I'd be careful/hesitant about changing the transmission fluid.

 

Careful with adding marvel or ATF or any cleaner to the oil....you might consider pulling down the lower oil pan after that and cleaning out the oil pump pickup...because all that shit that gets knocked loose will end up in that screen. I'd probably do it anyway.
