What is the best motor oil?

It has been proven time and time again that these trucks are easy on oil.
If you want to split hairs just spend $30 and get a blackstone test. It tells you what you can not see.
Then report the results on here.

I run Mobil 1. It's cheap and supposedly good. Have 4 Toyotas on it and never an engine issue.
 
Delo 400 15w40 all year. It cleans the engine very well and produces good UOA's.

Read what Blackstone.com has to say about using or not using synthetic oil. Their website contains a lot of real info.
 
Chevron Delo 15w40. I called in an order thinking I was buying 3 jugs because of the price.....turns out it was 3 cases. I have a 3 year supply now. Oil pressure is marginally higher now. It was cheap like borscht.
 
Mobil 1 Ow-40 from Walmart with 10,000 mile change intervals. For mineral, any HDEO 15w-40 for temps above 30f. For cold weather, a name brand 5w-30. Change at 5,000 mile intervals for hard operating (short trips, lots of idling) and feel comfortable at 7,500 mile intervals if you drive a decent amount on the highway.
 
I read an oil comparison article this week, can't remember which website, and it boils down to changing the oil frequently.
All oils tested were good and within a small margin of each other, no matter how expensive or cheap they were.
I change the oil every 5000-6000 miles (synthetic, T6), because that's what I am used to doing for decades on all cars, no matter what the car or oil manufacturer says.

Might've been Blackstone, because they were braking down everything, engine wear by chemicals and deposits, oil additives... everything. Can't remember.
 
what ever is on sale in 15w40 and change it regular with good filters !!!!.. (only thing that gets the thin stuff is the wifes avalon hybrid)... the cheeper brands are usually just end runs of the main brands. I know for years Napa and Walmart was the end runs for what ever was in the tanks at the bottler.. All oil today is really good, depending on which motor you have you may want to run a zinc additive as the epa nazi's have taken all the zinc out of the motor oils and therefore if you have a flat tappet cam there is very little cushion.. I use lucas engine break in additive about half a bottle for each change.. Makes any motor I have with a flat tappet cam run quieter..

Newer motors have much better bearings clearances and can run alot thinner oil, most of my stuff is old and has alot of miles so the 15w40 works and the detergent the diesel oil has keeps the inside really clean.. Most of the newer motors were designed with the modern 0w20 synthetic's in mind..

Meh, as long as you don't 'roll coal' on anybody, you're just smart enough to see the merit of glowplugs :cool:

"Bro trucks" driven by Hollister wearing hipsters, that's another story :slap:

Oh hell no, I don't roll coal, because, I know how to set up my motor and the only thing I know about Hollister is the hells Angels . My diesel has no glow plugs it a Cummins 6bt not a Power joke or Douchemax
 
My vote is clean recently changed oil is better than "better" oil with dirt flying around in it.

I use Mobil 1 because it's everywhere. My engine doesn't leak oil with it, I can get it at most every gas station, and my wife's car has it too.

After spending the stupid money on rebuilding my motor last year, this is the only oil that touches my LX460.

switched to the Turbo Diesel Mobil 1 5W-40 a few years back after I read NLXTACY's thread, I also started to eat more jalapeno's around that same time, coincidence?

Exactly. The best oil is the oil you change regularly, period.

Synthetic is great for extremely hot and extremely cold environments. Otherwise quality cheap oil that meets the Manufacturers recommendations is all that is needed.
