Someone told me to use a full bottle 32oz (1 qt) during my next oil change, subtracting 1/2 qt of oil.

So instead of putting a full 4 quarts of oil, put 3.5 quarts plus 1 quart of oil stabilizer, making the total 4.5 quarts.

Do I want 4.5, or 4? (Use 1 quart of stabilizer plus 3.5 quarts of oil, or 1 quart stabilizer plus 3 quarts of oil)

 

PS

The directions on this product are pretty hard to understand.

Does that mean I want to add the full 4 quarts, plus 1 quart stabilizer?

20% of system capacity (4qt) is .8 of a quart.

Is that 4 quarts plus an 8th of stabilizer, or 3.2 quarts of oil plus an 8th of stabilizer?

 

Put the Lucas in in place of 1 quart of oil.If it holds 4 quarts, put in 3qts of oil, 1 quart Lucas
I have used it in all of my vehicles for years. Good stuff.

 

ok thanks, do you put it in before the oil or after?

 

Does'nt matter, I usually put it in first.

 

yea dont go overboard with it and do it when the engine is already been ran so its warm, set the bottle on top of the engine for awhile while your draining the old so it can loosen up some, its super thick if its cold. re check your oil level again the next day cause it can take a bit for it to get around and you may be over or under. ive used this stuff in many vehicles, when i first got the dakota there was some engine noise, but after the first oil change using lucas everything got smoother and more quiet.

 

although i only use half a quart at a time with the oil changes so that the bottle lasts two, its still gonna help
