Diesel oil ?

[fliesitdies]

Hello,
I normally use Delo oil from Costco. Now they carry Kirkland brand oil. Just curious about your opinions. Thanks for your input.

Costco is THE LARGEST retail distributor of oil...  i would not be surprised if the Kirkland Brand is rebranded Delo 400. Private labling of booze, canned food, and toilet paper al fit this model.

I made the same switch about 2 oil changes ago.  I haven’t noticed a difference, except in my wallet, good price on Kirkland oil.

"Kirkland Signature Heavy Duty Diesel 15W-40 is blended by Warren Distribution (WD) which is the same oil marketer that makes Walmart's Super Tech brand. Warren Distribution blends Mag 1 oil which is their own house brand."

I bet I get flamed for this... 

The oil marketing guys have really gotten into everybody's head.  Bottom line is - find an oil that matches or exceeds the API spec's required by your engine (CJ-4, etc.), and change it regularly.  If it is a diesel from pre-2004, you may choose to add an additive that restores the sulpher available in oil back then that isn't there now - but unless you're running that engine at a high load all the time, it probably won't make a difference.

I use whatever I can get at the right price for my diesel engines on my boat and change it every 300 hours. Delo 400, Mobil, or even the Napa brand bulk barrel I can get up here in Sitka.  17,000 hours on the main and 25,000 hours on the genset, still running strong.  I'm a little pickier for my 6.0 due to the HPOP and injectors, but still just run basic dino oil. Haven't had an oil-related issue on that truck in 160K.

Find the right grade and API spec of oil for your engine, and change it.  You'll be fine.

I put Wally oil and AM/PM gas in my rigs and they run like new.  Sure, gas and diesel are different, but until I blow something up or read a legitimate story from someone else I can't see spending more for a promise that nobody can actually demonstrate.  Show me the data and I'll change my mind quickly.

I run gas trucks to 300k and then sell them to guys that run them for who knows how much longer.  I think doing the maintenance is 1,000 times more important than what you do the maintenance with.  At 150-200k I get all spunky and do a double oil change - change the oil, drive it for a week and change it again.  After that, the oil is clean for the next dozen changes if not more.

I wouldn't hesitate to buy any Costco house brand.  From my experience, you will get a solid value.

Gas and oil are funny things, they all come from the same place and everyone has their own secret sauce.  With oil, you can research the additive package and confirm it is within specs.  With gas, I don't think anyone has ever shown that any additive does anything other than lower your checking account balance.

Walmart sold DELO cheaper than COSTCO did. What’s the Kirkland diesel oil sell for a gasoline now?

T6 is not an apples to apples comparison since it’s a synthetic line. Nonetheless Shell Rotella T4 is another good choice as are most of the majors top shelf 15/40’s.

Is the T6 better than the Delo 400?  I switched to T6 when costco stopped selling DELO, and it costs me about $21 more per oil change,  not significant it it is a better oil.

Synthetics will give you longer service & change intervals. Better is subjective

Do a Bearing test with just about any type of oil,  they all run about the same as long as viscosity is the same. 

The key with any oil is to change it on time every time.  Driving habits dictate a lot of oil change intervals.
