I buy Motorcraft oil at Wal-Mart. They have Motorcraft filters too.

And that is all I ever buy at Wal-Mart.

 

I always use Motorcraft filters,oil is Pennzoil but I don't think there is a lot of difference in any oil.I have used the Tech oil from Wal Mart and it looks a little different,but I don't think it would hurt anything.I started using Havoline in my 93L because Advance has had it on sale a few times.The big name oil probably has additives that the generic oils don't which probably affect how it performs at extended oil change intervals.If you change oil evry 3,000mi. or 3 months,I don't think the Tech stuff would ever hurt anything.

 

Pennzoil evaporates in my truck. If I use it I have to top off the oil quite a few times between oil changes. I may have to do it once with Motorcraft oil.

I've also read that Pennzoil's (and Quaker State's) quality has dropped so far that they are often worse than some of the house brands.

 

So here is mine! Walmart has a lot to lose by selling BAD oil under their brand name. The distributing company they purchase from is just that a distributing company! They purchase their oil in bulk from Shell or penzoil or whoever gives them the best price on a train load... Then they repackage the oil into however's cans and ship em out. Using Walmart oil will get you good oil from any number of manufactors. I never hesitate to use oil labeled by any parts house or other supplier that does not spend a lot of money advertising their oil. The price we pay includes all the advertising done for that particular product. Why should we pay more for a product just because the product has heavy advertising?
As for filters they have the same liability Walmart does for selling a BAD product. I use Fram every time if it is available. If not then whatever is handy.

I for one, prefer to rotate brands anyway, then I don't get caught with a situation in which it has always had the same oil, and when something else is used, it creates an oil burner due to the additives being different and making a glaze on the cylinder walls that the different kind of oil takes off because of the change in additives.

 

The additives are there to maintain viscosity, ph, reduce viscosity and keep particles suspended so they don't gunk up the top of the cylinder heads.

Changing brands is not going to cause a glaze if they oil has good quality additives.

Glaze is a result of poor lubrication.

 

Actually, Warren is a blender. They buy all the parts and mix up the oil themselves. They are in Omaha.

This part is very true. In Texas and a few surrounding states, Wally oil is made at the Shell plant in Houston.

Yep. They buy from however is cheapest.

Been running "house" brands for decades. Never any problems.

Were we separated at birth?

 

I wasn't talking glaze from changing brands, more from NOT changing brands, like these guys that never run anything but Pennzoil and then someone else gets it and runs something else in it. Happens all the time on the heavies, they run nothing but Rotella, the next guy wants to run Delvac, now they have an oil burner.

 

jschira is right.Warren is BLENDER/MIXER of Wal-Mart's SuperTech Oil.Warren also has their OWN brand of oil called MAG1.Warren also makes products under the Polar name.
Warren Distribution/Warren Performance Products buys their base oils from a company such as Shell or Mobil etc.
After they get the base oil,the actual recipe is Warrens.
Warren Dist./WPP is not Warren Oil Company of North Carolina.Warren Oil Co. of NC bought Coastal Unilube from El Paso Corp. in Jan 2004.The company is now called Warren-Unilube.
Coastal is the maker of Advance Auto's house brand of oil.
For an oil to carry the API Donut and certification,the oil must be tested by API and meet and or pass their testing standards.
The API Donut and specifications are not mandatory for a motor oil,they are voluntary,makes you wonder about Amsoil.
When an oil is submitted to the API,it has already undergone substantial testing by the oil manufacturer.
The cost to get an oil API certified costs thousands of dollars,once again,API certification is not mandatory.
It would seem that any SL oil will do the job it is required to do for 3-4 thousand miles.
Oils that have more additives may be better suited for extended drain intervals.
I have been using the SuperTech for some time now with no real problems.

 

Most likely, the recipe belongs to the additive maker.

Companies like Lubrizol and Oronite (Chevron) sell additive packages. When you add the additive pacakge to a certain quality base oil, you get an oil meeting API designations. You can tell Lubrizol what base oil you want to start out with and what API designation and viscosity that you want, and they will design the package for you. You can start out with really cheap base oil, but the additive package gets more expensive, so it can be cheaper to use a better base oil and add fewer additives.

I've been running the Super tech oil for 7 years now, and haven't had any oil related failures yet. I have noticed that it tends to apperently vaporize a little easier, as I switch to a more reputable brand for a change, and don't lose the oil as fast. That's about my only complaint I have.

 

Interesting.

Just changed the wife's '02 Volvo yesterday. Just a tad over 5000 miles (25,000 total on the car). Oil level was still in the top 1/4 of the dipstick mark. Wally 10w-30 (old and new).

 

Likely depends on the motor, and driving style, perhaps, that was on older engines and regular speed of 70 mph for at least an hour at a time, sometimes extended hours. I generally lost about a quart over 5000 miles.

 

I have two chevys in the garage. An 01 3/4T suburban and an 04 3/4 H/D. they both have a light on the dash that comes on and sez it is time to change the oil. The 01 sub has always lit up a little after 5,000 miles but the newer 04 H/D does not lite up until about 6,500 miles. Both have the 6 litre engine and we purchased them both new.
I have not investigated how the thing works but I don't change the oil till the light tells me to.

I'm guessing, but I would think it's tied to the odometer maybe.
