I was wondering if I should add lucas oil stabalizer or not? Pure Synthetic Oil Stabilizer
I have mazda 3, 2012 2.5L 5-speed automatic transmission. I am using mobil-1 0w-20 oil. Wondering the pros and cons of doing this? If so, do I just put in 1 less quart of oil and add a quart of this?

Was wondering the same thing for my transmission fluid. Lucas Oil - ATF Conditioner | 4WheelParts.com

 

You're already using the best oil money can buy. Why do you want to add crap to it?

 

Obviously my knowledge level is not the best and thats why I am asking. Thank you...

 

I'm using every 6 mo. Liqui Moly MOS2 with European formula Castrol Edge 0W-40. Just my preference with direct inject engine. 2011 Mazda 3S

 

Just use a good synthetic oil and you'll be ok, not really a need for additives.

If you want better protection, move up to a higher quality oil like Amsoil or Redline (Group IV and V syn oil respectively).

Personally, I don't like the 0w20 weights, and use 5w40 for better wear protection.
