Say you decide you want Pennzoil Conventional and go to the local oil change business.... you tell them you want Pennzoil Conventional and they pump it in.... is this any different than buying a sealed bottle... My friend was told my a mechanic (when his 1st gen durango seized) that you should never use bulk oil since "you never know what that transport/tank truck was hauling prior to the bulk oil delivery" ---meaning, that truck coulda been delivering some other type of oil, and that the Pennzoil Conventional 10w30 bulk would be contaminated with whatever was in the tank---- any truth to this?

They guys that deliver our bulk oil at work, haul nothing but engine oil for various shops, they may have carried a different grade or blend in the previous load I agree, but the 10L out of 2500-3000L(depending on the compartment) isn't going to be enough to effect the product being delivered. In the case of our delivery guys, the compartments are marked for each brands/grade on the trailer's controls itself so we don't even get a mixed blend ever. Your friend doen't work deliver petroleum products for a living, otherwise he'd realize that their are many designs of tanker trailer, all of which used for carrying different types of product, and companies do not use a trailer to carry different types of product for various quality and safety reasons.
My concern with bulk is that some of the additive may have settled out. I've seen moly settle out on some of the Quaker State Torque Power I have sitting on my shelf. Some good vigorous shaking mixed it back in.
I have strict standards on what I use in or on my car.
However, there are millions of people that get their oil changed at Quick Lube places, see nothing but bulk oil and have their cars make 200k, 300k, 400k and higher mileage marks.
If changed regularly, all should be gravey.
Now recycled oil, is a different story.

Bingo. My guess is that describes most drivers, and they still average much, much better engine life than many years ago.

+1 chevrofrek. If bulk oil is stored too long, the additives can settle out. General motors warned dealers about over buying more bulk oil than they could use within a specific time. So you have more of a potential issue if you go to a small dealer who moves very little oil and uses large bulk (55 gallon) containers.

Does this mean that the people that are getting their oil pumped into their engine from a nearly empty tank are getting a lot more additives/detergent in their oil?

Additive fallout is a concern.
Eddie's mention of GMs warming brings to mind an issue I had while managing a truck shop. Our oil supplier had mentioned on more than one ocassion to not over order oil for our bulk tanks. Think he said we should try to work out a 30 day rotation if possible.

What if the bulk truck previously carried used oil? eeeew! I wouldn't want to put any oil in my car that was contaminated with used oil

Think of how many vehicles are in the road in the US, now think of how many "Joe Consumers" are out there that take it to a Jiffy-Boob style oil change place. These guys all use bulk oil to fill 99% of the vehicles they service. The vehicles run just fine for many hundreds of thousands of miles.

Many bulk oil formulations are "professional" blends which have more robust adds. I've always gotten BETTER perfoming Valvoline oil from my local chevy dealer in bulk OC than what I put in from the bottle. What's leaching from the plastic bottle into the oil? Silicones, ethylene dienes?

I remember reading a story on here a while back of a guy who ran his Chevy truck over 1,000,000 miles on bulk Pennzoil. Here's the story for anyone else that hasn't seen it:

YES spartuss and that is not good. Oil is forulated to meet specifc requirements.

How are you judging this? UOA?

I dont judge overall lubricant quality with a used oil analysis. If you do your fooling yourself.
I judge oils by OTR performance and fuel milage. Been drivin for over 40 years, should know a good oil by now.

I've never heard that before. How did you determine the bulk oil from your dealer was better than out of your bottle?? What test method did you use to verify that statement is all I'm asking.
