Not trolling, but all things being equal, why not just use SuperTech for everything?

Not trying to start a forum war, but I've been wondering, if you're someone who changes oil frequently, does it make sense to use anything other than SuperTech synthetic? I've never used it before, what I've used previously is Mobil1 AFE, Valvoline SynPower, or Castrol Edge Titanium. My goal is to maximize engine reliability.

Is there really any difference using something like Castrol Edge vs SuperTech (both 5w30)? If both are D1G2, SN+, and GF-6 certified, and you do changes every 4,000 miles or so, what's the downside? I don't mind paying more if I'm getting my money's worth, but lately everything has been around double SuperTech's price. So if there's truly no benefit, I'd rather not throw away money.

Engine is an FA20DIT in a WRX. I take LSPI very seriously and I also know TGDI engines like to shear oil hence the frequent changes.

I often buy whatever is 5qts for less than $20. NAPA, ST, QS, M1 with rebates, etc. I change when the manual says to in the Subaru (6k which ends up being at the 5-7k mark) and I split the difference of the 5-10k interval with the Toyota, usually around 7-8k. It seems to work ok. I could get all fancy with a $10-30 UOA, or just change it a couple times per year for $20-25 including filter. Any oil will be fine in my situation in my opinion. I could probably even use *gasp* non-synthetic and neither car would care. But I'll go with syn since that's what they're supposed to run on. I do the same with my oil filter. $1.50-$4 unless, like yesterday, they're out of the cheap Frams. Had to upgrade to a Tough Guard for the Subaru. Maybe keep it on for two changes since the box says 15k. Hmm...decisions...
 
With so many annual rebates out there, it's possible to use major brand synthetic oil for less cost than Supertech. Mobil 1 annual rebates work out to about $14 per 5-quart jug... pretty sure Supertech syn is more than $14. Pennzoil has regular rebates too.
Or just wait for the Stop/Start formula to go on clearance 😷 - have not even touched my RGT or VME yet …
Still working through my M1 AP and TSUV jugs …

Just like any other product, people have their favorites and the great thing about free enterprise is we get to choose what we want. Even if something is considered better, or more cost effective, doesn't mean everyone will automatically make the same choice. People have preferences that sometimes are wildly different than yours or mine.

true, but there comes a point when someone else’s choices call into question their capability to make decisions for themselves. people that like blue cheese, for instance.
 
The price of ST is on the rise all of the ST synthetic i saw was “faced” above what appeared to be the correct location and was all over 17.xx per 5 qts
The 12 qt econo box was over $41
Just like the kirkland oil prices are rising. good deals are getting harder to find.
 
For some reason, I have just gone from a complete oil nerd to the guy who now puts ST 5w30 High Mileage full synthetic with a Fram Tough Guard filter in my 2 older vehicles. This from the guy that drove all over metro Detroit to "score" discounted German Castrol "green" when they discontinued it and you could still find it at Auto Zone (some here may remember the"green elixir of the gods") when it was all the rave (I think I ended up with over 60 qts. of the stuff...took awhile to use it up..good oil but what was I thinking?). Next was my Mobil 1 obsession and finally Pennzoil (oh yeah...only Redline lubes.in my tranny and diffs too...just drained that out last fall and replaced it with...you guessed it...ST synthetic for the diffs but staying with Redline for the trans). The simple fact is I'm coming up on 66 years old and am now retired. I'm still driving my last new car (2010 Suzuki Kizashi AWD) with 104k miles which more than meets my current needs. Fact is, it's the best and most trouble-free car I've ever owned. It's been maintained to BITOG standards. It'll last awhile more. When something breaks that won't make sense to fix considering the value of the car (next to nothing...even in this market), I will have to give the 'ol girl up (think CVT). So far, good maintenance and sensible driving habits have avoided any costly repairs. I didn't retire rich...able to get by with some left over but won't be buying new again. The house is going to need a roof and furnace soon (can't believe the roof estimates...double just a few years ago). Considering the fact that I drove less than 4,000 miles last year I think I'm good (before retiring I was driving 30k a year ..had my Prius for that). I don't frequent the site much these days but it's nice to check in once in awhile...just to see what's going on.

That's what I do with our 2 older/higher mileage vehicles (teenager's) too - ST HM oil and ST filters. There is just no reason for me to spend anymore on those cars for DIY oil changes that get driven 5K or less a year.
 
Why would I use Super Tech when I can get better oils for cheaper?
The ST stuff is $15 for 5L I believe. M1 with $10 rebate is going to be a touch cheaper (I see M1 for $22-24 for 5L). Less hassle for me I suppose for what could be $2. Better oil is the whole crux here - what is "better" about those other name-brand oils in the use I have (teenagers driving a '08 Lexus RX350 and '13 Ford Focus picking up groceries? Sure.

If you need an API SP / ILSAC GF-6 / dexos1 motor oil, ST is just as good as anything else on the market. They even have a 20k mi rated oil for goodness sake.

Now, if you need Euro Specs.........

They sell it up in Canada - I'd use it in my Atlas.
 
Did my oil change with ST Synthetic 5W-30 on the Silverado this last week .
First time using it. Truck only gets driven a few times a month. 5k miles or less a year.
I don't need to spend more IMHO for 5K miles and a port fuel injected engine.
I'll be using ST or Havoline Box oil from here on out on this old truck .
 
If they made a 5w-40 A3/B4 oil I would.
Here you go, but like someone mentioned, it’s here in Canada.
