Which oil would you never use?

I wont use any oil that comes from China, or any non name brand oil, as long as I have a job.

I wouldn't blame the oil, perhaps a lack of it, or just the Ford in it is to blame.

For me it's Castrol GTX because my car died using that oil with 3-4k mile OCIs. The car was a piece of junk and it probably lived as long as it was designed to but the rings cracked and the oil was guilty by association.


What did Castrol GTX have to do with your cars engine? If there was a problem
it would of gave out with any oil. Whats with all these people jumping on
Castrol? Look at all the other oil companies using GRP III and calling it
Synthetic. Isn't Pennzoil Platium GRP III ?

You're probably right the oil had nothing to do with it but did you ever see a guy with two black eyes. I don't need to be told twice.
I certainly don't want to prove that it was the oil that caused the engine failure when it's easier to change brands.

WOW. I started driving in 1960. I have used either Pennzoil or Castrol except for 3 years, 2001-2002-2003 where I used Mobil 1. I have never had an oil related issue. Am I lucky or what. I use German Castrol now and have been since 2004.

I would never use a non detergent oil.

Comically enough, the only engine failure Doug Hillary ever had was caused by the oil that would eventually become GC.
 
Probably Amsoil, Redline, RP, any of the boutique oils. I'm sure they are great, but the cost is too much. My driving style is pretty laid back, 95% highway. I've been using havoline, pennzoil and pure-guard and been very pleased. I don't like the MLM of Amsoil either, though I did see it being offered at Runnings F/F. I don't understand why such a great oil is marketed that way, not something I gravitate to.

Why would I be concerned with what may have happened in Australia with an oil that wasn't available here and contrary to the inference was not German Castrol yet. I don't know the circumstances, I wasn't there. Now I do know my circumstances for the last 49 years so I think I'll stick with what I have been doing.

I do however love Amsoil everything.

And Tony caused me to write to QS and tell them as someone who used QS for over 30 years I'll look for another brand after that stunt.

Take care, bill
 
pennzoil, I know its good and all but my father was a mechanic in the 80s early 90s and was a hardcore valvoline guy. lol. only pennzoil i use is in my transmission but im switching that soon.
 
I don't use any of the mysterious looking oils on the shelves at dollar stores and gas stations. Ya know, the kinds with labels that look like a kid printed them off at home for a school project and the names you've never heard of.

I also will probably never use any of the boutique oils because price vs performance.
 
Any API SM rated oil is going to be GREAT for 99% of the cars on the road.

If you have a sports car, or turbo car, then synthetic or what the book recommends.

I wouldn't buy non rated oil.
 
I have used a boat load of different oils over the years. I can't say that there is one I wouldn't use. Other then the ones at Dollar General and stores like that.
Heck, I wish I could find some Wolfshead on sale at Sams Club or Costco.

But right now I will not use PYB or PP simply because of what a fad it has become on this board. I read thread upon thread about how great this stuff is. C'mon UOA, VOA or not, it can't be much better then most the API rated stuff out there.
I ran a 5000 mile OCI on Super Tech with zero issues whatsoever.
I've use Advance Autos house brand with no issues either. My engines started every day, my fuel mileage was good, and my motor didnt burn a drop of any of it. The heads were shiny new looking under the valve covers as well.

But I do like to try different oils to see if I can really tell a difference anyway.
 
Anything sa or sb rated.

And for those of you who won't use castrol products because of advertising, well you can't blame a company for knowing there audience.
 
I know my dad 1926-1998 and a few others from that generation Ive talked to would not use Quaker state or Standard oil products I think that would be Esso.They said it Sludged up engines.I remember him saying when they tore an engine down that used those oils you coulds pick it up in "chunks".I'm a GTX/YB user.Never been a fan of Valvoline.I'm sure however it's just as good as the others.To each his own.
 
A straight-weight in the dead of winter.

I even 'worry' on really cold days if 5w30 dino is good enough...
 
Well, there is no oil I can 100% for sure say I would never use because I don't know every instance where I may need oil and what oil is available? I would obviously prefer not to use a 20 year old bottle or some of that really cheap crud WalMart still sells( Accel?? ). However, in a time of dire need, any brand of oil would be acceptable. Just means an OC immediately.

With that said there have always been 2 oil companies on my list I would not consider using their product if any other alternative was available( excluding the obvious like the cheap Accel stuff at WM ). A 3rd has recently jumped onto the list but it could come off if they made a change...

1 - ExxonMobil. Their Mobil oils are over rated(IMHO)so they are not a 1st choice anyway. 2nd I can't stand the company especially since the gas price gouging fiasco of the last few years. They profited more from the raping of the American consumer than any other company and thus I refuse to give them a dime of my money unless no other option is available to me.

2 - Amsoil. Just don't like the company's marketing tacticts. Decent oil but don't want to give them my money because I find them unethical. With that said I do have Amsoil 4-stroke oil in my outboard I am trying out thanks to Pablo and the great price. Only product they have I will use on a regular basis if it does the job for me this winter. I tried it only because there are not many other marine synthetics to choose from. If it does the job then it will be used because it is really my only option. It won't lead to me using other products from their line however.

3 - Castrol. I am adding Castrol to my list until they stop with those stupid "think with your dipstick Jimmy" ad's. Castrol GTX has always been my #1 preferred conventional oil and Syntec is ok for blend and full synthetic. Until that obnoxious guy whacking people with a dipstick and hollering Jimmy goes away I refuse to use their oil.

Ppeople may think these are stupid reasons and that is fine. You are free to feel that way just as I am to feel as I do.

Castrol makes excellent oils, as do many other companies which various people have issues with.

The oil I would never use: SA rated [censored] which can be found in almost every store in the country and which is all junk. Also, I almost never buy store brand or off brand oils. With so many great deals available on top quality name brands, why mess around with who-knows-what?

WHAT THE .........!
 
Don't want to start anything on the boards. I think my comments that I find their marketing unethical is enough to make my point.
