Major reduction in oil consumption. Was using 1 qt every 460 miles. After the treatment it uses 1 qt every 2200 miles.

2007 GS 350 AWD, 235k miles.

This sounds like an ad for Berryman's Piston Soak!

did you pour it inside the spark plug holes?

This is what I did:

drain oil and leave plug out. Let engine cool down completely.
4oz b12 in each cyl.
let soak 5 hrs, jiggle crankshaft occasionally.
another 4oz b12 in each cyl.
let soak 5 hrs, jiggle crankshaft occasionally.
another 2oz b12 in each cyl
let soak 5 hrs, jiggle crankshaft occasionally.
vacuum each cyl and put a couple drop oil in each.
flush crankcase with 1/2 gal kerosene, install drain plug
Add 5 qts oil and 7.5 oz b12 to crankcase
Run engine for max 15min or until at operating temp
Change oil and filter.
If any b12 leftover, put in gas tank, max 1oz per gallon of gas
I used 4 cans b12 ~$20

Would you be able to share your detailed experience after you did this? Any noticeable difference in driving, other than the oil consumption reduction you mentioned? Does the car feel smoother, MPG’s get higher, that type of thing? Let us know.

I didnt notice any other changes after the treatment. It's my sons car and he doesnt keep track of mpg, He has commented that the car is driving very good.

I completed a second trearment on 2/24/23. I used the same products and procedures as the first treatment.

I am totally shocked that 2,458 miles after the second treatment the oil level has not dropped at all. The engine has consumed no oil. I Cant say how impressed and pleased i am with the Berryman's. Perhaps any other similar product would have done the same. I dont know. But what I do know is Berryman's fixed my problem.
