any one here ever use super tech oils ?

the salesmen at my job always tell the customers that once they switch to synthetic you MUST keep running it.

that is the biggest load of BS i have ever heard. i ran mobil 1 in my mustang at first then switched to motorcraft once the blower went on.

my Ranger and Xterra run the cheap ass bulk oil we have at the shop. it is Kendall oil. i had never heard of it before we started using itand it works just fine on my 250K plus Ranger.

See thats what I have always been told by mechanics and sales persons. I have owned a few older muscle cars. I had a 1973 Ralley Challenger (which I wish I still had seeing as they go for like 80 grand...) and a 1973 Plymouth Duster Twister Edition. I always ran conventional oil in every car I have owned. Also Rugster just because my car is bone stock doesn't mean I dont know **** about cars. This is my first Mustang that I have ever owned and its bone stock because I have only had it for a few months. This being my first Mustang it came with Mobil 1 full synthetic from the previous owner. That being said I have NEVER ran synthetic oil in any car I have had in the past so I don't really know much about it besides the fact that it lasts a little bit longer than conventional. My dealer, mechanic, and the guy at the parts store all told me 'once you make the switch to full synthetic its never good to go back". Having no experiance with synthetics I assumed they were all right. But apperently and according to you guys they are all wrong thus I probably came off as an idiot for posting that stuff about synthetics. No biggie. Now I know. Thats why I joined these forums to learn more about my car, ha.

Hi All,

IMO the whole change your oil thing every 3k over here in the USA is just another way for the oil companies to stiff us all for cash

Can someone tell me they do this over here?? because in the UK and most of Europe you only change your oil every 12-16k why is that? I used to use Mobile 1 over there too

I have been running Penzoil Full Syn from when I bought the car new and now I have almost 60 k on the clock and is still fine. Also I just switch back to Ford motercraft oil full syn last week so only time will tell..

later

I don't know anything about this supertech oil. However, I am also seeing a lot of misinformation on here that not only doesn't have any objective scientific value, it doesn't even have a foundation in logic. Several of the statements such as I ran it 300K miles an it runs fine, you can or cannot switch between synthetic or conventional, or I added it to my transmission and it fried in 3000 miles have no value. Let's just stick with the facts and this might be easier. These are going to be very general statements and yes I know I'm leaving some things out so feel free to add in anything that might be relevant.

1)what is the difference - in general, synthetic oil has a higher shear rating, higher temperature, and lower ash content than standard oil. All of these together means it has to be replaced less often.
2)If you don't have a good filter, the best oil out there is quickly going to deteriorate to useless.
3)The 3000 mile rating is horse manure. Oil should be changed when it is either dirty, has broken down or load or lost it's additives due to temperature or load, or has sat for a long time and absorbed moisture. There is no hard or fast rule here. For the best information, use your vehicle in different environments and then send the oil in for analysis. BMW and Mercedes have oil changes up to 15,000 miles on some of their vehicles under certain conditions. However, their engines may have lower tolerances, less blow by, etc... The point is that several factors need to be included in how often you change your oil.
4)Switching between conventional and synthetic doesn't make any sense financially or performance wise. Yes you can do it but conventional oil will have high content of ash, etc and may leave more residue in the engine that gets mixed in with the synthetic when it comes through. Stick with one or the other. If you don't need synthetic or you don't plan on keeping your car for 300,000 miles, use conventional. Yes, I know many cars have seen conventional run 300,000 mile but if you actually look at the deposits and wear in the engine, you will see that synthetic will have a lower wear and pretty much no deposits at 300,000 miles. In a conventional car, I run a Mobil 1 filter and Mobil 1 oil and change it at 10,000 miles. I have run it 15,000 miles if I have a lot of highway miles on there. On my Mustang with the blower, it's between 3000 and 5000 depending on oil color. If I race that weekend, fresh oil goes in. Send the oil in to be analyzed several times and find out what's happening to the engine at different mile changes or different oils.
5) I used supertech and my transmission blew up - My question is why? What broke in the tranny, did you drive any differently, did you measure the wear before you put the supertech in, etc..., You have no basis for a cause and effect of the failure so therefore it has no value to this argument.

The reality here is that without any more technical information on the Supertech, I couldn't tell you if it's better than Mobil 1 or worse than Canola Oil. You need to compare the information put out by their scientists to see the difference. Go to an Amsoil or Royal Purple site to see what the difference is with the top of the line oils and then work your way down from there. Those companies also have a lot of information on other company products. There is a lot of people who have published the exact facts on the differences in oil and again, oil filters. I can't stress the the filter issue enough.

Without more information on your car, engine, usage, or 100 other factors, it's hard to make a general statement on oil. I personally use synthetic on everything because it works out cheaper in the long run if I keep the car 200,000 miles. I have also seen engines raced on conventional oil and raced on sythetics. It's a huge difference but it's also a high shear/temperature environment that doesn't really apply to the street unless your car sees 6000 rpm's frequently. If you are into being environmentally concious, it's also less oil wasted although most oil gets recycled nowadays.

The best objective study I ever saw on synthetics was done on taxis in New York. They ran synthetics for 60k miles and sealed the engines. On engines that had regular filter changes oil, no oil changes, and just added oil when needed, there was no measurable wear. On engines they didn't change the filters on, engine wear was equivalent to conventional oil with regular oil changes. However, what they found out was the filters had broken down a long time ago and the engine effectively had no filter for tens of thousands of miles. What it did prove is that synthetic basically doesn't break down,

pretty much i say just spend the couple bucks extra and put a good oil in.

Supertech oil is made by Quaker State. Oil is just like batteries, there are only so many makers. Our "Honda" bottled oil at the dealership is made by Mobil. Carquest brand is made by Valvoline....
As mentioned earlier, As long as it meets the API requirements its all good.

my grandpa never changed the oil in his truck (now my truck) for 50,000 miles.. he was a solid believer in changing the oil filter every 2,000 miles and topping off the oil..

now the truck has 110,000 miles and it still runs like a raped ape... and i even did a H/C/I swap on it she looked beautiful inside..

corse i change the oil every 3,000 miles now that its mine lol

btw 83 F150 2wd with a 351 roller

way to go! screw oil changes all together lol.
The ranger at my old job didn't have an oil change for 70,000 miles...or a filter change but we throw them away at 100k any way..which is usually about 2 years.
