Cheapest oil I have found

[Tim McKay]

In my area, all oil retailers continue to raise their Diesel oil prices. It is now at ridiculous prices.
I started looking for the lowest price on quality Diesel oil.
I found this at Costco. $32.99 for 3 gallons, or $11 per gallon.
Of course they dont make it, so is what they are selling quality stuff?
See image below, it meets the Ford specs for Diesel Oil. I’m guessing its Rotella.
My mechanic once showed me a 55 gallon drum of of Ford Motorcraft oil, on the back of the drum was a Rotella sticker. So I know Rotella is open to rebranding.
The pictures are due to the Costco sight requires members to log in.
Hopefully this helps someone.

If you have a local Tractor supply, check prices for your local store. Local store pricing does vary a lot even within the same state.

If you want to mess with a 5 gallon bucket, $38.99 (at least based on here) for 5 gallons ($7.80/gal):

Both of those oils are made by Warren. Same as Supertech. Uses the Delvac add pack. Good stuff!

I buy Walmart engine oil by the pail. I think the brand is Tech 2000? $50CDN

I have run it in gas engines (5w30), and in my diesels (15w40; Chevy 6.2, Ford IDI, 7.3PSD, 6BT cummins) without any issues for the last 10+ years.

I’ve used Harvest King brand at Rural King several times in the past couple years. I believe it’s $9 a gallon regularly, maybe $16 or so for a 2 gallon jug.

Warren makes very high quality oils at low rices( little to no advertizing). Warren is every bit as good if not better than the name brands.

Walmart Super Tech Heavy Duty SAE 15W-40 Motor Oil, 2 Gallons....$20 for two gallons.

At Walmart, I spring for Delo at less than $12 per gallon.

Bi-Mart has 2-1/2 gallon Dello 15w40 for $27.99. being a chain with their add posted on line I wouldn't think their price would very per store.

I've been running Supertech in everything I own for years, except for my K5 as that one has a modified 489ci stroker big block in it.

Though I may have to check my local TSC..that's a few bucks cheaper per gallon than even the WalMart stuff..
