Engine: Walmart Engine Oil ??

[G T Joe]

Walmart Engine Oil there major brands like Valvoline Quaker State Mobil the regular oil not synthetic use base recycled oil and then add new additives and sell it as new oil where if you buy it from a parts store it does not use a recycled base oil does anyone know about this ?

If it's recycled oil it has to have that stated somewhere on the label.

[Gunslinger]

I’ve never seen recycled oil sold retail. To my knowledge the only places you find it used is for fleet use.

WHERE did you read That?
Maybe on the Costco Website?

I have heard of "Blended" Oil (Partial Synthetic); part Synthetic and Part Regular Refined Crude.

Walmart oil is blended by a few different refiners depending on which part of the country you live in, but most is supplied by Warren Oil Co. Walmart's oils will work fine in most engines and it is sold at a good price. Bud

Nathan (Nvonada} makes a very good point about oil and flat tappets in this post, comment No. 6. Worth reading.

I remember buying recycled oil back in the 90s from an auto parts store. I don't remember which one. I think it was in a white plastic quart with "oil" and wt. in black letters.

I know there is no difference in the name brand oils that Wal-Mart sells from the same oil in a parts store. Probably even come from the same distributor.

Used to be able to buy recycled oil in glass bottles at the local M&H discount gas station. There was a small independent refiner that specialized in recycled oil. I also recall that the Champlin oil that was sold as the Gibson's store was recycled as well.

For a very short time one of the chain stores was carrying a Valvoline-recycled oil, in a rave green bottle. It was supposed to carry the same warranty as did their product crafted form virgin crude. It also had the same ingredient package as the regular oil. I bought and used some on one occasion. The problem was that it was about the same price as regular oil and it never went on sale. A marketing philosophy like that seemed unsustainable to me, and within a year it disappeared from the shelves.

I use Walmart brand oil when breaking in a rebuilt motor, but then swap it out in about 500 miles. I prefer name brand oil, but am comfortable buying it at Walmart. Recently, I learned most 'additive packages' in all oil brands now comes from off shore, even Mobil 1, which has long been my favorite. I have also discovered Mobil 1 ain't what it used to be. Years ago, at 5000 miles in a Stude, it was still fairly clean on the dipstick. Noways it is filthy black at 5000, even on our modern brand 'x' cars. I have long used Mobil 1 in everything, and changed it at 10,000, even in Studes. But now considering either going to a different oil, or changing the Mobil 1 at 5000 in everything. Just the times we are living in.

I'm curious why your Mobil 1 oil is now turning dirty sooner. Perhaps it has a better detergent(s) package? That dark stuff has to come from somewhere. I'll be surprised if the oil itself (or the additives) is turning black.

I have used Mobil 1 in all my vehicles for ~30 years with no issues, but am now considering switching to Valvoline Racing oil as per the Cooperator experts in Turning Wheels.

BTW, not all synthetic oil is truly synthetic. Some of it is simply petroleum oil further refined until it meets the standards of true synthetic.

The additive package on all oils that have the starburst and a Dexos rating on the label have had major additive package revisions over the past several years which includes substantially more cleaning additives which are necessary for the late model engines. If the oil doesn't start to turn dark, then the additive package is not working. I don't believe that Mobil 1 or any of the premium synthetic oil suppliers would risk reducing the additive package in any of their oils. Oil will if the additive package is working properly, the oil will start to turn dark in short order in any carbureted engine due to the rich fuel mixture that is required to get the engine to run smooth without stumbling or hesitation. The excess fuel has to go somewhere and if it isn't out of the exhaust, it's going past the rings and into the oil. Bud

I have been using Mobile 1 since 1997, in Studes, modern cars and motorcycles, with motors new and old, including newly rebuilt Stude motors I then wore out and rebuilt again. I have always liked how it Mobil 1 took so long to change colors, as mentioned above. But it has changed recently, now it's more like dino oil, black as tar in 5000 miles in ALL our vehicles. Something has changed, I dunno what, but doubt it is the detergent. I recently rebuilt a 352 I had rebuilt prior in 1997, and used Mobile 1 after initial break-in in 1997. Upon tear down it was clean as a pin inside. I know their additives now come from off shore, and suspect it is related.

Similar for Mobil 1 oil filters; any model number with suffix 'A' is made in China, and most all of them now have suffix 'A'. Similar with ACDelco filters, and likely most others. After 25+ years of use, I have now lost confidence in Mobil 1 oil, and their filters.

When I was in high school during the 70's I worked at a local chain store selling general merchandise (a pre-cursor to WalMart).

Since I knew how to work on cars they put me in the automotive department and I endured the same bunch of morons coming in week after week asking the same stupid question... "Isn't this (insert national brandname) just old oil you guys filter in the back room and resell in new cans?".

My answer was always the same, "This is brand new oil, and you are an idiot". My boss backed me up for a couple weeks until someone with clout whined to the main office. They made me leave off the idiot part, so I made sure my facial expressions told them they were idiots for believing such crap.
