Some will say its a waste of money to do it that often. I say its a waste of money not to.
Amen. The recommended fluid change intervals are based on a lot of different variables which I won't go into here. For cars & trucks down here in Houston, TX take a manufacturers recommended interval time/miles and cut in half as a minimum. We have heavy duty conditions down here. Anti-freeze is just one component in our fluid inventory. I have a master mechanic friend of mine that has one of the best shops down here and he has many clients that bring their cars & big pickup trucks to him and they take the recommended schedule, cut if half, use BG Products and it's common that these vehicles get 250K - 400K miles on them, depending on the user. Fluid maintenance is everything in keeping things working right. Oh, and deep clean fuel injectors too, every 15K max.
As for me....everything flushed, renewed and changed out every 3-4yrs. max with BG products. If I put on a lot of miles it's 3yrs. It's pocket change to do this compared to what you'll pay to replace or repair any of these systems these days.
My 2 cents.
