First Oil Change

[OR VietVet]

Because I live where I work, self storage facility, I put very few miles on my rig unless I go to the coast or on another trip elsewhere. Even with the full synthetic oil and Wix filter, I always change at one year or 5k miles, whichever is first. No problems for many years on many rigs. You can change to full synthetic with no problems. Some turd once told me that after a change like that, I would develop an oil leak somewhere. What?

This does happen, but not directly because of synthetic oil.

It's usually on higher-mileage engines or those that were neglected WHILE running conventional. The leak is already "there" due to worn seals (from age and use of lower-quality oil). But, the crap oil and/or overly-long OCIs allows carbon and/or sludge to build up, bandaging the leak. Also, conventional oil molecules aren't as small and sleek as those of synthetic oil, so they don't fit through the tiny gaps in the worn seal(s) as easily. Switch to synthetic with detergents and the "bandages" are dissolved, allowing the smaller, sleeker and more slippery synthetic molecules to seep through.

So, using conventional oil to avoid or stop leaks is using it as a Band-Aid to prevent that which the use of it causes.

Thanks for this- I saved it in my cart, to be confirmed later. I've always wanted to switch to a magnetic plug but never remember to get one before my annual oil change. I'm not even sure if my pan has the original thread size since it has been Helicoiled. I should've replaced the pan when I had the motor out.

this is for the Denali. Not sure if nnbs is the same. I need to put one in the avalanche. It had one factory but when they did the warranty work for oil consumption, they put a standard one back in it for some reason

Oooooooh. Oh well, it being in my cart will at least remind me to get one. Or make my current plug magnetic. I could do that during the oil change. Just drill a 1/4" cavity in the plug and epoxy this in there: https://www.kjmagnetics.com/proddet...8d8uG-_eXEriLOu5WlHqz5uiEd8N0mfBoCgkQQAvD_BwE
