63K to many miles to switch to full synthetic ??

I buy the on-sale oil packages in Autozone, usually $39.99 for a 5lts. bottle of full synthetic (Valvoline, Mobile, etc.) and 1 K&N filter... I don't think filter is such a big deal if it's changed out every 3-4k miles!
But I do spend extra $ on a bottle of Lucas oil stabalizer for about $11.. worth it? idk.. there're mix feelings on it!![Roll Eyes](https://acurazine.com/forums/images/smilies/rolleyes.gif)

2/ but kinda outdated...
I think that article was from 2004 and companies could change a lot in 7 years!!
Red line and Mobil are worse than Valvoline and Purple Royal??

My phone is super low downloading that pdf but it sounds like the Amsoil bearing load test. No relevance to engine oil, I think it was used to test grease years ago. In one test they showed that bleach did better in that test than any oil. Gonna read it in a few.

They are made exactly the same, except the KN has usually $1 markup over the Mobil1. Probably because the KN has the nut welded on the base of the filter hahaha!
