Johnsen's 4688-8-12PK Octane Booster - 7 oz., (Pack of 12)

Q: Is this for cars or offroad/small engines? Safe for oxygen sensors?

I use this product to increase the octane rating of "regular" gasoline for my turbocharged car which calls for 92+ octane. 1 or 2 bottles per tank of gas raises the octane level to this level. the cost is a lot less than the average of 50 cents per gallon more for "premium" Say 15 gallons x .50 = $7.50. This product costa alot less to accomplish same. Never had a problem.

Q: What would this 7oz bottle bring 87 octane up to?

Depends on the amount of gasoline added to. ask Manufacturer

Q: Does this contain MMT or foul the spark plugs?

The label doesn't state it has MMT. It says it does not contain alcohol and is safe for catalytic converters and O2 sensors. I have used it with every fill up and 87 octane gas for over a year and have not had any pings or fouled plugs. My infiniti runs great, has plenty of power. No noticeable difference in performance. Hope this is helpful.
