Recently used Lubegard Bio/Tech Protectant for 1st time at oil change on my high mileage old japanese 4 cyl and really pleased / impressed pretty much right away because noticed two things pretty much immediately (and all controls same = same motor oil brand/grade & same oil filter as before adding LG b/tech plus same fuel grade from same filling station , same tire psi)
{1} engine a good amount quieter
{2} car seems to be running just a smidge smoother / peppier down low (twist/torque)
Will continue to use product & not too pricey either and avail locally for me
