thought this would be super cool and a good learning experience for all so here it goes....I have a 2017 Tahoe and I replaced the oil, transmission fluid, and filter with these products

this should help maintain and prolong the engine life as I cannot afford a new vehicle at this moment.

also going to buy a bunch of Mother's products, anyone use their products?

gonna make my Tahoe shine!

 

I dont use Amsoil, but I do use full synthetics. Amsoil has a great reputation, however, its just that I am not certain its better then what I use.
