Kirkland Oil

Yep, and they deliver it to my house for free. 4 oil changes for $100 + filters and Walmart carries OEM filters too.

It only stays in the truck for 5k miles so if it isn't perfect it's plenty good enough!

 

Yeah, I reread it and still missed it. 5th time was the charm though.

Kirkland oil is only 3 years old.

Context of "Only" is what threw me.

 

And this right here is what really matters. I bet Blackstone labs has plenty of data that supports all oil is ok for most people using most engines under most conditions.

 

Kirkland oil is probably like Kirkland alcohol. It's a name brand with the Kirkland name

 

Be more interesting if a sample is sent at 10k miles, or after a year.

 

Agreed but I'm not likely to go that far

 

Think I'll be giving the Kirkland 0W-20 a shot. I've had two Toyota Care oil changes since Jan 21' and I'm at 18k now so I'll be shooting for 5-6k intervals. I'll be sure to update any results. Hope to see some Blackstone 10k test results one day...

 

Just bought 60 qts last week for about $190 after tax. Pretty good deal imo

 

Yes, as discussed earlier in this thread, it is Warren Distribution.

 

Kirkland is more than sufficient for the needs of these trucks.

 

I have supertech in my supercharged Mustang that is a year old (the oil, motor is 22). I'm about to change it. Maybe I'll send in a sample to check the health of the engine.
