Walmart Supertech oil

Jay4200 · Jan 17, 2006

( Ive used Castrol 10W-30 for 18-19 years..changed every 5K miles. Never had a bit of problem. IN FACT..I would have used it in my new Kubota..but its NOT "diesel rated"...so that made me go on the hunt for something that was.

Is it good?? I have no idea. It was rated very good once upon a time. But there are people using it under MUCH more severe conditions than Id even attempt and they arent having any problems......it will do me for sure. )

I've used Castrol GTX for 20 years too - I guess I'm just a sucker for their '80's vintage "formulated for small engines" commercial with the 'lil motor screaming in the background (I just love that sound). Oddly enough, at least according to the the 'oil bible' document, it tests out to be OK, but not great. Coincidently, (and to help keep this on thread) Castrol GTX measures out to be quite similar to Walmart Supertech - go figure. It looks like GTX does hold up a little better when hot.

After 4000 miles ,I had the local Cat dealer perform an oil analysis. The test came back showing all the adds used up. TBN 1.5. at 4000 miles tells me the oil is junk. The TBN should have been higher than that at 4000 miles on a low milage engine with no problems.other add. #'s were also low leaving my engine with very little protection.I did a search & warren & Q.S. makes the stuff at wal mart specs.

Thanks for the info. I thought I would try and save a little money by switching from Mobil-1 synthetic to Supertech synthetic, but after about 1000 miles the oil not only looked dirty, but it smelled old. Now, I'm talking about a vehicle that after break-in has only had Mobil-1 synthetic oil and Mobil-1 filters installed. I got to thinking why spend $50k on a vehicle and then try to skimp on one of the most crucial components of maintenance and operation.

Since then, I have only used what I had left to lubricate the chain on my gate operator and on the kids bicycles. /forums/images/graemlins/wink.gif

Good choice to stick with mobil 1. Mobil 1 is a group 4 while superjunk is a group 3.It only cost a little more to go with a good oil. I'am glad that you saw for your self that you wern't saving any money using superjunk. I will be switching to Amsoil as soon as my change is due.I just think the ware protection is / will be better with Amsoil.

( If someone has an old Yugo with bad rings and loud knocking connecting rods, it would be a most outstanding oil for it.)
Hey SkyPup,
I knew a guy who had an old Yugo...that thing was sooo slow...
instead of a speedometer it had a calendar in it!

TXDPS recently started using Amsoil w/add'l filter on all of their patrol cars and are expecting to make up the difference by less oil changes. I believe they are looking at 25k between complete oil changes. On my unit I was changing the filter and replacing a quart of Mobil-1 every 5k-6k miles, depending on look and smell.

Walmart, like some other posters stated, bids out their oil suppliers. Different parts of the country get different blends and suppliers. I think that in my area, the southeast, Warren does a lot of oil for Wally World. It meets the specs and is good oil. AutoZone does the same thing with their Costal brand. It's Warren. I use Rotella in most of my stuff. My 96 Caddy's got over 176K on it. I believe that a Consumer News Magazine did an oil analysis test several years ago and found that oil, for the most part, was good up to 8,000 miles but recommended 6,000 mile changes as very conservative. The tests were conducted in New York using taxi's as a fleet of test mules. It's ironic that my Caddy's GM oil minder typically shows changing at around 6,000 miles. Lot of oil wasted out there.

Turbys ,I wouldn't run dino or a group 3 synthetic over 3000 miles with out an oil test to show how well the oil is holding up.It didn't hold up in my case that's why I no longer use it .It's not that I wasted the oil , it's that the oil was changed because the oil it's self was wasted per. oil test.

I don't use it, I'm an extended run synthetic guy. But my father uses it and has for years. I changed the oil in my mom's Honda 2 months ago, it had 6000 - 8000 miles on it, was black as coal and seemed thick. I sent a sample out for testing and it came back fine. Needless to say I was shocked. It still had some life left in it. The only anomaly was high sodium, but I attribute that to a very old air filter.... I'm **** about maintenance, but I certainly didn't get that from Dad. He has several pieces of equipment that never get oil changes, they simply get topped off a few times a year. It's fairly common for his equipment to be so low you cannot get a reading on the dipstick.

I'll keep that in mind, but truth be known, I kind of like the old blister.
