Naahhh.

Wouldn’t want to be anyone else!

30 Quarts of HPL EURO 5W-40 will last three 10 Quart OCIs for a total of 6000 miles; yes, 2000 mile OCI. About 1 year. The 24 Quarts of AMSOIL Signature Series 0W-20 will last four 6 Quart OCIs for a total of 12,000 miles; 3000 mile OCI. About 9 months.

Most of the things thst I do that get me labeled “insanely wasteful” and other colorful phrases are done so that I don’t beat myself up for not doing those things…so that I sleep better at night.

I asked my stealership servive center director if my truck had break in oil in it and he told me they no longer used break in oil, but rather the OEM Mobil 1.

I watched an oil break in protocol used by a poster. The premise runs along the same lines as ruleof72’s post. He was explaining that he had taken his daughter’s new car snd changed the oil himself at 500, then again at 1000 then again at 3000. He didn’t discus later OCIs because he wanted to...

Oil Filters: Amsoil EABP90 (Bypass filter 2 Micron), Amsoil EAO26 (Full flow filter 20 Micron) Oil: 10 quarts HPL HP SAE 5W40 EURO Synthetic Performance Motor Oil 2018 GMC Sierra 1500 Denali Ultimate trim. 65K miles.

I took delivery of another 12 Quart case of HPL 5W40 Euro High Performance.

I do shake my inventory and each quart before it goes in my engines.

I have no reason to doubt you.
