I had to return to the my dealer in Phoenix and got a free oil change and took a friends car to a shop.


Both mechanics advised me of this without being primed.


Use the highest quality oil I can buy and change filters more regularly than the oil. He said your RP oil (I use Royal Purple) will last 6K easily but buy a 2nd oil filter and replace it every 3K miles.


Thoughts?

 

I run RP, and just do a filter and oil change when the OLM tells me to. Cheap insurance. I work my truck hard. My local Walmart carries the 5-quart jugs of RP.

But yes, most full synthetics can handle more mileage if you just change the filter.

One of my previous mechanics would drain the Mobil 1 out of my engine, and put it in his personal car, knowing the oil had plenty of life left.

 

Lubrication is the cheapest form of insurance.

 

I don't understand why filters are getting so dang small small means less surface area and a quicker restriction of flow....

 

Probably getting smaller because they are cheaper to make.
