I’m sorry. I didn’t know I had to come to your highness for approval.

Well you don't need to seek anyone's approval but as this product has never before been a topic of discussion its just curious something about it is posted now. Call me skeptical or suspicious just seems to be out of place in a way.

P.S. If you had even opened your browser before the snarky comment, then you would have immediately seen that Kirkland is Costo’s private label. How someone could make money off of that is beyond comprehension. Sigh, the internet.

to be honest, they could give it away and i would still not use it.
i have no use for synthetic oils.
everything i own gets valvoline all fleet plus 15-40.
294,000 miles on a 351M, 496,000 miles on a 7.3 idi, 194,000 mile son a 7.3 powerstroke, and 323,000 miles on a 5.4
all have never been opened up.
if synthetic works for you, i have no problem with that. but i use what works for me.

Unless one or the other has changed the Kirkland and Walmart’s Supertech were identical products when the Kirkland first came out. They are both still produced by Warren.

I always like to see actual technical data on oils posted. It’s interesting to me, although I do believe that if it meets the spec for your engine it’s good. The search for “the best” or I only buy brand X no longer interests me.

Kirkland, Walmart Supertech, and I believe one other label are identical high quality oils made by Warren oil. They are the bargain of the oil world.
There is no universal standard for semi-synthetic, by the way. Is is 5% syn, or 1%? There is minimal value to semi, other than the fact that you are putting clean oil in your engine.
If you are using dino oil, that is 1980's technology. it's your engine, but you aren't on to some secret hack, and you aren't doing your engine any favors. The fact that your engine runs for a long life is more of a tribute to excellent modern engine machining.
When I worked for a Nascar team, we torture tested oil to failure, and the more that we abused it, the more that you could see the superior lubrication and scuff protection of synthetic oil. You would struggle to work your street engine anywhere that hard. What we found was for street service, all available oil is excellent, synthetic is much better, and you should use whatever colored bottle that you like.
