Not sure if it is the best oil, but apparently it is the smartest oil on the shelf. It features those "intelligent molecules". LOL!!

Thatís what I have in the Santa Fe at the moment. Nothing bad to report. Itís a good deal lately. I would use it again if I didnít already have a bunch of Pennzoil Platinum in the garage.

Castrol GTX Magnatec is a good oil. I have used it couple of times. 17.88 for 5QT jug is a good price.
Pennzoil is coming with a deal starting 1st Feb. $10 MIR on 5QT jug. Walmart normally has the best price on Penn Platinum. $10 MIR will make it cheaper than Castrol GTX Magnatec.

Current Fill in my Rogue

This oil has been gabbed about all over this forum. The Semi syn showed stellar wear #s on for turbo engine(s) - if that means anything to you. The Synthetic IIRC has been AVERAGE.

My experience was (on the picky qr25DE Nissan motor):
The Semi syn Magnetec was a superb fair-weather oil, but the synthetic did NOT allow my engine to make high rpm ppower/torque for whatever reason (likely high shear, low-ish viscosity.

The best oil for warm season Ive run ( last summer) is 10w30 QSUD NON DEXOS - - BY FAR!

I will not run Maggy Syn again - until I forget I said that in the distant future smile

Remember "FULL Synthetic" does not mean synthetic, it means majority group III - which is dino!

Where did you get this info? I didn't see anything online. That would be a great deal.

Do not buy Pennz before Feb. 1, 2018. http://www.pennzoil.com/en_us/promotions...XRpb25hbDE4Lw== so you can take advantage of the rebate.

Got it on Black Friday at O'Reilly for about $10 / 5qt after rebate, finally found a way to use up those rebate gift card from the past. 5w20 synthetic huh? I guess I'll use it in place of 0w20 in warm climate.

Do you prefer a Group IV API SH or a Group III Dexos1 Gen2?

All I see is save $10 when you bring it in for an oil change at participating locations. Nothing for DIYs.

http://www.pennzoil.com/en_us/promotions/do-it-yourself-oil-change/promotion-9.html might be a better link, without the frame-session info in the URL.
Note Pennzoil doesn't have a link on their promotions page to the upcoming Feb. 1 promotion yet, but it exists as a web page right now.

The QR25DE is a picky engine? Please explain that. And perhaps define picky.

If you were unable to get proper power out of the engine, I think you may have had other issues.

Magnetech is one of the best value for oils on the market these days. I have used it forthe past 3 years on my Ford pickup and my daughters 2010 Focus in fact I just changed it out ta Christmas and with a 9,000 something oils chnge interval the oil was barely below the full mark on the dip stick.
