Input on changing 15w40 brands.

[thejudges69]

QUESTION,,, you are going through 50-60 gallons oil a year in personal Truck or truck(s)?... how many trucks and how often you change oil.. I currently have one truck 2017 3500 6.7 cummins and go through like maybe 6 gallons a year with 10K oil changes as a full time RV doing like 15K miles year....

I average 60-90k miles a year 10 gallons each change. 15k mile intervals. I’d like to go 20k but my engine shears oil fast. So I have to shorten the intervals. 15k seems to be the sweet spot with Kendall oil.

Probably the best bargain in HD oil right now. It's a blend but a darn good one. As a bonus, it's API SP for mixed fleets also.

Am I wrong to think that mobile is cheap cause of cheap products used? Everyone else inflates costs and mobile always seems to stay cheap. I don’t understand how or is my thought process wrong here?

That's interesting. My father used to buy TR but I thought it was in the normal range for pricing. I think they have a conventional and synthetic blend. Either way, I don't think you'd want to extend OCI's 2.5 time to match the cost.

Please let us know what you chose.

I like their chassis grease. Red with gold flake. But their 15w40 I priced it with my TR rep and was 238.00 for 5 gallons if I recall, maybe 208….but it was twice what im paying for Kendall and my reps price gouging me for Kendall. I just couldn’t justify that for their oil.

From your list, my top 3 would be:
-Delvac Extreme (full syn)
-Delvac 1300 Super (blend)
- Delo 400 (conventional).

The Delo synthetics and blends are also quite good, IMO.

I'm biased towards Valvoline for HD oils because we use them for internal testing. But they aren't on your list and honestly Valvoline doesn't seem to have very good distribution in the commercial lube sector. I think Commercial stuff is a real focus of the DELO line, so you might have very good luck there.

I have not found valvoline anywhere locally for sale. Tractor supply shows it online but not in stores. I do recall the 10w30 maybe was the factory fill oil for Cummins several years ago.

I just responded to the thread about NAPA Synthetic. That might also be a good option. NAPA sells bulk oil, sometimes at great sales prices, and its been said that its re-bottled Valvoline. Might be a good option, especially if you can get a commercial discount. You can set up an account with them without a credit account which is what I do. Did this at the Ford dealer as well and there is some major savings to be had with little more that a business name, address and phone number.
