Post your latest oil or filter purchase

[tired]

If you changed oil once per year for 10 years and there was 5% of 5 qts left behind (0.25 qt), then theoretically the residual oil left from the first oil change would only be 0.05^10 = 0.000000000000098%. The oil left behind from 3 previous OCIs would still be only 0.000125%. Even leaving 5% behind from the last OCI isn't going to hurt anything. Some auto makers recommend changing the oil filter every other OCI, so that would add even more oil left behind.

Don't tell him that there are probably still 10 or so molecules of the factory fill still circulating around. He might switch to 1000 mile OCIs!

I don’t know of any case of extreme PM beyond this.
With that filter setup and boutique oil (+2 quarts over stock) just running to the OLM limit would not produce any additional wear …

2500 mile OCIs with HPL Euro?!??! Wow... Insane waste of money and resources.

I bought 24qt of Pennzoil Platinum 10w-30 at Autozone for $3.90/qt. Not a smoking deal, but it will keep my 02 Chevy 6.0 happy for a while.

Good oil - Good motor - Good price

Honestly - this day and time - the 3k crowd could do a decent semi in those big V8’s …
It’s the 4 bangers eating themselves and the oil makes it go down easy LoL …

Just bought this to try in the Impreza next year. Love the grammar. "We just make it perfected better". Can't make this !@#$ up.
