Costco has Delo on sale for $9.33 / gallon
Chevron Delo 400 SDE Heavy Duty Diesel Engine Oil (https://www.costco.com/Chevron-Delo-400-SDE-Heavy-Duty-Diesel-Engine-Oil.product.100340379.html)
Limit six. I wonder if I can keep going back and buying six more per register trip. I go thru a LOT of diesel oil and sometimes its cheaper in five gallon buckets at fleetpride but I like delo better than the house brand they sell.
Yes you can go back, also DW can buy at a different register the limit.
Awesome. Looks like the limit is six cases of three, which is much better than six gallons. Yay costco!
Costco registers do not prevent going back over and over for any item, even with the same credit card.
Our Costco had the delo 400LE 15w40. Not same stuff I assume. Ok to substitute?
It is the older spec. oil. Would be within specs. for your engine. I use what I have left over from the last sale in my 1981 DT 466 engine. Bought the oil with new specs. for the FT.
Found it a few miles north in Brandon. Wondering if the LE might be worth keeping for Hydraulic?
It looks like this is an Online price only. Has anyone purchased in-store and received the same discount?
Yes. Bought 6 of SDE and 6 of LE in store. Check store by phone tho. Same item # but two different spec oils.
For everyone but the very newest engines:
New designation diesel oil recommendation by Cummins and Cats replaces/supersedes CJ4 : CK4 15-40. NOT FA4 which is only for very newest engines.
Is Rotella T6 ok for my older 8.3? Lookin' to change soon...
