Costco Kirkland Signature Full Synthetic Motor Oil 0W-20 & 5W-30


This is the first time I’ve seen Costco’s very own Kirkland brand motor oil (scroll down for photos). This is fantastic because I am still one of the few people that still like to change the oil on my vehicles. For years I would always buy the 6 quart (6 individual quarts) of Mobil 1 from Costco whenever I needed it & I want to say it ended up being between $3-$4 per quart depending on sales. This is so much cheaper and it comes in (2) x 5 quart bottles. I much prefer the 5 quart bottles because I like to reuse the bottles to dispose of the old oil & it makes filling 1 bottle much easier. (As opposed to 6 small ones).

My local Costco carries the 0W-20 & 5W-30. Honda’s & Toyota’s commonly use the 0W-20 & many passenger cars, SUVs, light vans and trucks use 5W-30. This is unbelievable cheap for FULL SYNTHETIC MOTOR OIL. It comes out to only $2.20/quart of (I repeat) FULL SYNTHETIC MOTOR OIL. If you’ve never change the oil on your car, I suggest you do for a few reasons……

  • Save money
  • Save time (I can get mine done in about 30 min. It takes me longer to drive down and wait at the local shops)
  • I know exactly what filters & oil I’m putting in (high quality usually)
  • Gratification of doing my own maintenance
