Kirkland (Costco) 5w-30

[Ckck]

Thoughts re. this full synthetic oil? 10 Qts. $27.00 delivered. Definitely a good price but, is it a quality product?

Thx. again,

I'd run it for my typical 5000 mile oil change interval.

That's a great deal. I think I paid just under $40 all in shipped for a 3 pack of Supertech synthetic 5w30 5qt jugs a month or two back.

Copy. Thx. Ck

Probably the same supplier as Amazon Basics and SuperTech.

I bought some for our Equinox, it was $22.99 in the warehouse. 5W-30. Can't beat that!

Hello, definitely not a heavy hauler. #11k tandem axel trailer...

If you have a Cummins you need to use the proper oil; what you’re asking about is not. Believe the factory fill was Valvoline Premium Blue 15w40.

Bought 2 packs yesterday @ $21 and change ($3 off the reg in store price). You can do the math $2.10 per quart! Unbelievable bargain. I change every 5,000 miles with Biotech.

5w30 in a Cummins? The good news is most costcos sell Delo. But yeah Kirkland is a fine oil, I do believe they even pay for the api certs.

As said, in a gas engine with a 5k OCI I'd run it. That is a great deal! I also use 5k OCIs and I honestly don't think brand or type of oil matters at that OCI, so long as your using the proper weight. Just my .02

I'm running Kirkland synth in wife's Tuscon and in my Mustang GT. they don't have the right weight for my truck otherwise, I'd do that too. I just think the whole oil thing is way over thought. The internet makes it seem as if I don't use PUP my motor is going to catastrophically implode at 50K. If I have a particularly rough interval with lots of towing and hauling, I change my oil earlier. so with proper change intervals, quality filter, if my motor only lasts 200K instead of 400K then I admit I'm a moron but until then, I'm saving some money on synthetic oil that meet most specs.

Some would argue saving $225 per 100,000 miles is not worth the risk. But I don't think there is a real risk. and I like $225. A ram is not engineered and marketed to the elite buyer. It's marketed and sold to the masses. We are dumb and we do dumb stuff. We are also the idiots that review products. so if you sell a truck that's so delicately engineered to fail using appropriate grade Kirkland oil, you'll end up with a lot of 'this truck sucks' reviews and the company will lose sales.

or I could be wrong and I'll be out one Ram 2500, shopping for a Ford or Chevy....
