I use Lucas UCL on a continuous basis in my 2007 Civic LX sedan. My engine has about ~4,500 miles on it and will be due for an oil change fairly short order. I would like to add Amsoil PI to the tank of gas that precedes the oil change, but have some minor concerns about mixing the UCL & PI. I do not know if there will be any interaction between these two products.
Is it OK to combine Lucas UCL & Amsoil PI in a tank of gas?
