True conventional oils

Bunch of 10w30's and up.
Everything depends upon the definition of conventional oil. How is that defined?
If you are considering viscosity modifiers as a "synthetic base", then monogrades might be the last bastion where you may find an oil with only group I & II base oils.
For multigrade oils, there are conventional oils, but you'd have to consider the viscosity modifier to be an additive rather than a base oil to justify that viewpoint.
When I was formulating, I always treated the viscosity modifiers as a, relatively high treat rate, additive.

The non-detergent API SA still on the shelves is probably group I
If it doesn't say it is a blend or synthetic it probably isn't. It would be pretty weird cost/margin strategy for them to blend a product that is supposed to be fully conventional with synthetics.
I think he is talking Group III and I'm fairly certain a lot of 5W-20 oils had Group III in them within recent memory without being labeled a blend.
Personally I've never thought a lot of practical difference existed between a Group II+ and a 50/50 Blend of GII and GIII. If it looks like a Duck, walks like a Duck and talks like a Duck it might not be but it makes a pretty good substitute.
I think a lot of 10W-40 is still Group II in the USA.

5W-20 - Group II+
5W-30 - Group II/II+
10W-30 - Group II
I'm not sure how much of that still holds.
Consensus was the average 10W-30 was a Group II.

Some of the 15w40’s are going to be Grp2
They're just in the process of relabeling. When Valvoline decided to relabel Daily Protection people complained on Amazon. No longer selling real oil. Oil change places still sell Daily Protection as conventional, guess it's cheaper than having to change the signs.
About those touted Mobil group II base stocks? Don't know if this still applies to SP.

Most manufacturers still label their 10W30 and up products as Conventional, if not labeled Synthetic.
Castrol GTX for instance... 0W20, 5W20 and 5W30 are now called GTX Ultraclean and labeled Synthetic Blends. 10W30, 10W40 and 15W40 are GTX, without the "Ultraclean" moniker and labeled Conventional.

Well it's not a PCMO but we know for sure that Mobil Delvac 1300 Super does not say it's a Blend on the front of the bottle but does on their website. So it appears they have decided not to market the fact it uses Group III Base in it's formulation.
Harvest King oil is like $1.79 quart. If there are Rural King stores near you. Local mom and pop place near me sells Pronto oil for like $1.99 quart
Likely have to catch a sale of rebate. I've seen Tractor Supply Traveller's (WPP) for $9.99 per 5 qt when they have their sales but the 5W-20 and 5W-30 are likely blends. 10W-30 and above might be conventional.

Yes, most 15W-40s, 20W-50s and Monograde oils in production in the world are still full conventional a.k.a Mineral ( Group 1 / 2 )
