QSFS vs Magnatec.

[aquariuscsm]

My oil change is getting near and I have a half quart of each (my huge "stash" haha). I need to swing by The Great Wall to buy a big jug. Which would you all use and why? Yes, I'm that bored tonight!

 

[John9721]

QSFS

 

[Zee09]

Mag
Actually ST 20k...i did.

 

[samven]

QSFS, Its cheaper and good oil.

 

[SR5]

Which car?

If in doubt I always buy Magnatec, or more likely whatever is on sale.

Have you considered ST 10W30 full synthetic in API SP ?

 

[Luftmasse]

How do we know which one is better, and why?

 

[Revving2Redline]

QSFS - HM

 

[CharBaby]

All are good but, I think you already knew that!
Castrol Mag is good
QSFS & STFS(10Kmil/20Kmil) It's all good!
Buy by price at the time unless you need something superior for a reason like racing.

For a vehicle not driven often, I would choose Magnetic. Driven everyday, I would choose QSFS.

Neither. The best frankenbrew that's been working well in multiple cars is Valvoline Advanced with Magnatec used as the top off, more explicitly 1/2 qt maggie in with the valvoline.
Maggie doesn't do it alone and neither does the Valvo. They must be together.
I have read a couple other on here have tried and are running this brew,

I havent ried the new formulation, but if it sanything like the past I would prefer the QS over the Magnatec.
But with the GTL, IDK ...

 

[Propflux01]

I see a popularity of users here who claim Mag is the "quieter" oil. So there is that..

 

[aquariuscsm]

Sorry guys I didn't add more detail, I totally passed out for the night right after I posted. It was a long week! It's for my Accord. I have a half quart of each leftover. Walmart has both oils at the same price here right now.

Funny thing ARCO, I think the smoothest oil I ever tried in my Accord was a frankenbrew (I cant even remember what all was in it haha maybe QSAD, QSUD, and PPHM).

20w50 castrol magnatec

 

[SteveG4]

Either one. Take your pick. Both are great.

 

[53' Stude]

QS EURO 5w40 since I have like 10 5quart jugs of it

 

[4WD]

Since you have the obligatory 1/2 quart of oil elixir … just get ST …
You know one can’t put the elixir in elixir …

Haha nice!

 

[53' Stude]

Haha nice!

Yeah, I need to quit being lazy; and order a dozen more wix sample kits and send that EDGE 10w30HM in for VOA

 

[aquariuscsm]

That'll be a good one! That oil seems to never gets any discussion and is a total mystery oil.
