Nah. Meets all major specifications for the newest engines. But have fun paying extra for the big brands so they can continue to bombard you with advertisements that make you buy their products and make you (wrongly) feel superior for having done so.

For those whose vehicle takes 4 qt per oil change like mine (2012 RAV4 v4). The 12 qt (12-pack of 1 qt containers) might be a better buy. Though higher $ per qt ($3.2 vs $3.33) in comparison, you can get exactly 3 oil changes from the 12 pack & no concern about shelf life on opened containers. Although it makes pouring used oil a tiny bit more work/drippy.

You don't have to worry about shelf life, especially if you are changing oil every 6 months. The oil is perfectly fine sitting there.

Odd that the 4 takes so little of oil. The older V6 takes like 5.8 (going from memory) quarts which is a bit of a pain with the 5 qt jugs.

I don't know how the newer Toyota 4's are for durability but the 4 in the RAV up to 2011 (or 2012) was renowned for using an entire quart of oil between changes starting at about 150k miles. The V6 of that time frame is regarded for going 400k or more miles without developing oil usage issues. I have 270k on mine and it doesn't use any oil.

Same thing when it was on sale last time (two months ago). Costco associate checked the system and saw that 5w20 was only online and not sold in warehouse. YMMV

I suggest checking a warehouse if you can before you place an online order. Last time I got this deal, I bought online immediately and then noticed it was $1 cheaper in store. Not a huge savings but if you're going in a club anyway why not wait.

Basically forever. Well, much longer than the timeframe in which you'll use it, unless you plan on buying an entire warehouse full. Manufacturer's list different values, but they have an interest in putting a limit on a lifespan due to liability (CYA). Autozone says 8 years for synthetic, but again they have a vested interest in making you buy more oil.

I can't find any objective testing (e.g. test an oil every 2 years or something and see if the composition changes), but there are some anecdotes that very old oil (like 20+ years) can start to separate (usually heavy components in the bottom) and in that case to just shake it up.

Which leads me to what I wrote originally - don't buy enough oil for the next 20 years. I change oil in our vehicles combined maybe 5 times a year, so if I bought 10 jugs that would have me set for a couple years or so. That's enough that I'm comfortable knowing I'm saving some money, but not risking, for example, selling one of the cars in a year and the replacement uses a different grade of oil.

Just use 5w-30.

I do that for my customers car. It will work as well or better. Provides a little more wear protection as the car ages also.

YMMV. My point was for one item only aka going to Costco just for 1 thing. Nobody practically does that during Costco. Nobody.

Instead Costco shoppers pick up other things beside this which would make this deal worth considering.
Lots of people have gone to Costco for one item purchases. Speak for yourself and not others. However, that hasn't worked out very well for you.
