Harvest King All-Fleet 15W-40 VOA

[SmrtJustin]

Here is a VOA I had run on Harvest King All-Fleet 15W-40. This oil is on Ford's WSS-M2C171-F1 approval list. CITGO provided me an MSDS for this oil, confirming to me that they are the manufacturer. I plan on using it in an AMC 360 V8 with flat tappets that I'm mostly concerned about the potential for fuel dilution from it being carbureted. I have previously used Rotella T and Chevron Delo 400LE 15W-40 in this engine. The price of Harvest King is currently $12 for 2 gallons or $8 for 1 gallon at my local Rural King.

Thank you for sharing. You can't beat the price.

I would suspect that Super Tech 15W-40 comes from the same source.

When looking at VOAs and UOAs, what do the viscosity values tell me. On this UOA one viscosity at 210° the value is 77.8 while the viscosity at 100° is 14.98. If I was looking for a thicker oil, which values between oils should I compare? Thanks.

Worth the price but nothing special.
Store brand oils are typically value priced and typically have pretty weak add packs.
This is but one example.
Still, at six bucks a gallon, it's not as though you'd need to run long drains to get your money out of it.

You are probably right but I recall Chris142 having ST 15w40 in his Peterbuikt for like 2+ years and it was doing well

Supertech, Traveller, Lubriguard are from WPP, Warren Performance Products, not Citgo.
PQIA says they are fine.
Thanks OP for the VOA.

I wonder if you going to post lab test of used oil.
Thanks

Looks good to me, TBN of 8.7, Zinc at ~1100 ppm, and a touch of Moly at ~ 40ppm. With a KV100 of ~ 15 cSt, its at the thick end for sure.
