QSUD Problems?

[geekster]

I've had nothing but great UOAs in my Frontier. Really good. It get's short tripped to oblivion. Idles regularly.

I use QSUD in it a Fram Ultra filter and I installed an EZ Valve. I only put about 7.5k a year on it. I do a drain and fill at about 6 mos while only changing the filter every other change.

Our Sorento gets a change at 3700-4k for severe service and warranty reasons.

Forte...same as the Frontier.

QSUD is high quality, high performance full synthetic oil. Can easily go 8k miles between oil changes. Mobil 1 and Warren/Supertech/Kirkland turned black much sooner. Mobil 1 was dark after 1k miles. I believe QS and Pennzoil share the same formulation and are made by Shell.

Oil color doesn't mean much to many or (dare I say most) of bitog.

I will point out that you overfilled your crankcase by quite a bit.

Did the Mobil 1 taste worse too? Because that's an equally valid metric here if you are going to C&P this post in multiple threads.

I'd rather have an oil that gets dark as my belief is oil with good detergent package gets darker quicker. Just an opinion.

I've ran QSUD in my Toyota for 7154 miles did a UOA and it had a TBN of 2.9. Would have gone 7500 miles standing on it head. There is not a problem with this oil!

If no oil deals are going on it would be in my top three at its normal price of under twenty dollars at Walmart. The other ones being ST syn and Magnatec depending on my mood that morning.

What this^^^guy said.

Got a 5 quart container waiting to go into one of the Corollas at its next OCI....heard nothing but good things about this oil.

Well I heard lots on bad things about it here on BITOG so bad in fact I figured it had to be BS so I tried it and its great!

My 2017 Hyundai Sonata 2.4L non - turbo DI gas engine calls for 5W20 oil on the oil cap ... In my opinion , all the 5W20 oils in this engine stink ! In my Hyundai Sonata's case it does much better on 5W30 QSUD or other synthetics (as far as oil consumption and probably shearing as well) . Thus I have switched to 5W30 synthetic oils over the recommended 5W20 weight oil . I do not believe there is anything wrong with QSUD oil .
