For your Tundra, which AMSOIL engine oil are you considering?
For relatively low mileage, I would think the OE (priced at $5.35/quart for preferred) would be a reasonable choice. The XL is $6.80 and at your change interval, I don't see the need for the Signature.
One of the issues that I've faced with an 8 quart sump is that I've got to buy a jug plus 3 quarts, which eliminates the jug savings, for the most part. I've only got 20,000 miles on my Tundra, but the engine uses no oil between changes. So, I don't need top off oil, or I would buy two jugs...
I just bought 8 quarts of the XL for my Tundra, and it's about the same as two jugs of any other synthetic (free shipping, too, if you order over $100), perhaps less if you consider that I'm not driving to get it.
I should add that I use the Toyota filter, which includes the odd cartridge drain fitting and new o-rings. It's about $5 at the dealer.
I also really like the AMSOIL firearms cleaner. Does a good job, and leaves a bit of oil behind for rust protection.
And I use the air tool oil.
And the metal protector, that stuff is great.
Pretty much my thoughts on the Signature Series. The distributor actually recommended the XL series....kind of surprised me. On a side note, does 8 quarts fill your sump? At an even 8 quarts, the level is about half way between the dots on the dipstick.
