Question for oil collector

[tiger862]

How do you make a decision on which oil to use first? I have the oldest I bought was Valvoline Advance Maxlife Synthetic and still have 1 5qt with a partial one with 4 qts all are March 20 then I recently bought Shell Gas Truck 0w20 jugs (3), 6 qts 0w20 , 5 qts 5w20, and 3 qts 5w30 on cheap oldest being January 19. Vehicle takes 6 qts with oil change averaging 9 months. Thought about using partial 5w20 Maxlife and 2 qts Shell first but don't know if base would be affected since different companies as well as different specifications SN+ and Sp. All oils meet certification requirements although manual states 5w20 or 5w30.

I stopped hitting the oil sales a long time ago. All I'd end up doing is giving it away haha. My stash now only consists of a half quart QSFS 5w30 and a full quart Magnatec 5w30. But SP.

It's not like it's going to expire. It was in the ground for millions of years. If you don't use it for a few years or a hundred years, it won't go bad. Just shake the bottle good before using.

I understand 5 years is what oil companies state. Heck if you listen to ads this might be last oil as gov wants electric.

Once I hit 30 quarts in my stash, I started putting a label on the bottles with the date purchased. Fortunately I stopped buying oil by the quart containers and now only buy it by the 5 or 6 quart containers. So whenever I need to do an oil change, I just pick the earliest date I see on the containers.

I use any opened/unsealed container first, then by date. I'm not super worried though, as I believe oil can sit for many years without issue. I also have no concerns about mixing different winter weights, and even stepping outside of the specc'd weight in my old beater. I don't do that in the wife's new car though. I certainly wouldn't give a moments concern over using different manufacturer's oils in either vehicle.

Probably use the RGT first, I'm sure it was all bottled in March or April 2019 the Valvoline is probably newer.

I try to cycle through oldest to newest. First I pour in any open bottles, then top off with an unopened bottle. This keeps things simple on the garage shelf. No more than one opened bottle per viscosity.

Example: My CR-V takes 4.5 qts. I have .5 qt left in a jug. That 0.5qts gets poured into the 4Runner first, then a full jug, then part of another jug 6.6qts total. The empty 0W-20 bottles get flipped and the drip oil drains into the last opened 5qt jug. Next oil change, the opened 5qt jug gets used first.

That is what I am planning to do. 4qts Valvoline Advance Maxlife Synthetic 5w20 left 5 qt container and 2 individual qts Shell 5w30.

I do that all the time. The previous oil change in my motorcycle was 1 qt Mobil1 that I found on a shelf when I cleaned out my garage, 2 qts Valvoline left over from a case and 1 qt Castrol. That oil change took me through 7 states and 4500 miles on my 2019 summer trip.

I have no real rhyme or reason in how I use my stash for the most part.

I know my 0w-20 oils go into my Scion, 5w-20 oils go into my truck, 5w30 is for the Kia and older Santa Fe, 10w30 is for the newer Santa Fe, and any conventional or blend oil goes into my brother in laws truck.
Age of oil really does not play a part.
