it's avail in gallons, singular quarts and 12qt cases, i usually buy it by the case and depending on what im changing at the time i end up with spare quarts left over and the second go round ill either order another case or a gallon and supplement the lack of quarts in the gallon with one from the spares
across the board gals are cheaper than quarts but may not be as convenient, cases cheaper than individual quarts, i think a case of gals (i think they do that..) is 4 gals
think a case of XL (7500 interval) 5w30 is about 60 bucks
the 25,000 filters are 13ish
Gal jug of 0w30 (10k+) is like 32 or quart about 8 bucks
OE(normal+ interval) 5w20's about 48 a case
OE 5w30's something under 5 bucks a quart
I use the wix filters with the OE oil on those vehicles, the wix filters are a lil over 5 bucks
year membership is 20 bucks which gets you the discounted prices, which just look at the amsoil website for prices and youll see how quickly the discounted prices will make the 20 bucks back
If you're interested, get JJ's dealer # when you're ready to get up one morning with a bigass box of goodies left by the UPS man
For me, as many vehicles as I deal with all at the same time, it's worth it to me to be able to sit here and have Part number lookups, fluid type and capacities right in front of me via the amsoil "garage" system. If you live near a distribution system they'll let you pick your box up at the warehouse too which saves shipping costs on big orders
