Switching Oil brands?

If it didn't make any difference why do so many people on BITOG forum say oil usage has accelerated when they changed brands? My answer was stated above on post 6606 on this thread. I chose to remain conservative. Ed

I rarely agree with you however I do agree with this post.


I can say without a doubt every vehicle I own gets a different brand of oil at every oil change.
And a can of mos2.

My vehicles end up with astronomical miles and when I'm done with them they go to the wrecker.
Although I have noticed consumption with M1 products Castrol,pennzoil and Quaker state haven't shown any consumption at all.
I'm not easy on my vehicles either. They are an appliance,purchased to serve my needs.
 
Unless something has changed in recent years, the military switches brands all the time depending on which vendor wins the supply contract. I believe the military runs their equipment harder than any of us ever will (typically until the wheels literally fall off) and switching has not caused any major issues with their equipment.

My Dad used QS for many years--from the 60s onward, but switched to M1 sometime in the 90s and used it until he passed away. I used M1 in the 90s and then switched all over the place, landing with SOPUS in the mid-2000s until around 2012 and then went back to M1.

I have never experienced more or less consumption with any brand, but that does not mean it cannot happen.
 
Occasional changes should not be an issue but constantly changing brand is pointless if not for a solid reason. New oil needs seating period specially switching over from/to conventional and synthetic as molecules are different in size and uniformity. Each group should varies. This is also a reason I don't like overly extended oci as it changes. Now don't quote me on it. It is merely an opinion.
If one develops burning it is NOT that rings are damaged rather the oil is not seated. In heavy industry such as water plants, steam central HVAC, power plants that I have been involved with rarely they switch oil types. Consistency pays off. Once you find what works for you stick to it.
 
I change constantly and have no negatives to report. Buy whatever is on sale, clearance, or rebated.

My engine isn't managed by a corporation thats too big or bloated or can't make a decision.
