Engine knock/ping and oil burning - Berryman B-12?

I've tried pouring a cup in each cylinder sock for about 12 hours (make sure you charge the hybrid battery by holding the brake and putting it in drive and pressing the gas Intel charged to full) and it will smoke like crazy. Do it before your neighbors are up or after they go to bed once the engines running keep it running pumpping gas the smoke will dissipate.
Oli burn is about 50 percent better need to do it again.

Good question, as there is no smog requirement in Kentucky. Over the long term, oil consumption will clog up the catalytic converter, foul sensors, and generally add extra carbon deposits all around -none of which is cheap to fix or helps the vehicle run any better.

Spend $20 now to save $$$$ down the road on parts, labor, or lower MPG might be worth the gamble. Unknown if it will harm the engine or emission components, but others here have used chemtool before and I haven't read a negative (though the product #, their method or application could've varied).

If you're using 1qt per 2000 miles, there is the possibility that some of the piston oil control holes aren't completely plugged up and addressing the issue sooner might keep you from reaching 1qt per 600 miles, or potentially reverse some of the consumption issues all together. Others here claimed to have reversed some of their consumption after piston soaking with acetone, which is an ingredient mentioned in the chemtool data sheet.

Will using the chemtool for a few tankfuls, an oil flush, or a piston soak be enough to fix the problem once and for all, doubtful.

Approximately how fast do you generally drive on the open road? (increased speed can correlate to excess oil consumption)

What brand/type/weight of oil are you using, and how often are you changing it?

 

Wow! That is insane – 30% more.

The pricing structure here is around ~4.5% more for 91 AKI compared with 87 AKI. But given we are talking the equivalent of US$5.35 for 91 vs US$5.12 for 87 (as at today's prices and exchange rates), you guys are streets ahead of us in terms of affordability.

In terms of miles, I get an extra 125 miles per tank (500 mi vs 625 per 11.88 gal) on 91 AKI vs 87 AKI. (Remember also, we do not have the fuel bladder tank, so it is relatively easy to use 11.88 gal (45 L) and refill 11.88 gal. No gas gauge worry either, it works reliably.

By my calculations, using 91 AKI, it is ~5% more expensive to do the same miles in US, if indeed 91 AKI is 30% more expensive than 87 AKI. MPG will improve, though. You should be able to easily average 50 MPG, with a winter/summer range of 48 - 56 MPG.

 

My 4 runner sounded like it had a knock when I pressed on the gas. Wound up being the spark plugs. Old old are your spark plugs, and are they the right type?

 

They are old but I have seen much older. My other question still stands, are they the correct plugs for the car? I have seen people using cheap a$$ plugs causing problems so often...I could write a book.
