Around here a bottle of lucas fuel injector cleaner (Small bottle for 1 tank) is about 5 bucks no more. On sale as low as 3 bucks for 2. But still no match for what I have seen Redline Oil's SL-1 fuel injector and carb cleaner. Tha stuff is AWESOME!!! As far as lucas oil additive, simply put by chemical makeup which is available from the MSDS (Material Safety Data Sheet) it is *******ly identical to 1 FULL quart of STP. So check prices 2 bottles of STP may be cheaper. Heck for that matter so Valvolines Oil Treatment. Get the basic version under the NAPA logo cheap. But heck add one bottle of STP to a 5 quart system of 5W-30 and you get 10W-40 so save the money and just put in 10W-40 to start with. For the whole bottle might as well reach for the properly blended 20W-50 that is not susceptible to foaming as other oil are when the additive package gets messed up with LUCAS.

Think I am whack search for the old Consumer reports article and find out that oil labs confirmed the STP change trough Oil Samples sent for Oil Analysis. And as for the Chemicle makeup goto the MSDS forms available online for STP, Valvoline Sythetic Oil Treatment, Lucas, Napa Mac's Oil Treatment (Made by Ashland AKA Valvoline) yeah yeah the systhetic one has some other stuff but the vast majority of the product is the same and after adding you are jsut making 5W-30 a 10W-40 so why not but 10W-40 and save the difference. But you goto one quart of the stuf and you might as well just go ahead and put in the peanut butter known as 20W-50 and save yourself the dime. Ohh but the car only calls for 5W-30 or 10W-30 well sorry your the one changing it.
