The members of this page have been impressed with Primrose 405....and I have always trusted the opinions of the members here. However, I am one of those see it to believe it kinda people.
Well I was ordering a case of delvac 1 from avlube and I decided to try some 405. My truck had developed a very lopey idle even when warm and I figured I would give 405 a try to see if it made a difference.
I have tried them all Howes, Power Service, FPPF. Howes let me down this winter after I got a nasty load of fuel.....it gelled while driving down the road.
Power Service and FPPF have been good.....as far as I can tell...no rusty water in the filter.....
Let me tell you.....I added a couple ounces of 405 to my idling truck before filling the tank. Truck was loping like crazy......sounded like a gasser with a big cam......by the time I filled the tank the big ole Duramax was purrin' like a kitten. Mileage has increased and starts are quick crisp and clean.
I am a very happy camper.....truck has 75K on it and it runs like new. This is the first additive I have used that has really shown obvious results.
I know this has been said many times but I thought it was worth repeating for the newbies.
Primrose 405 and AVLUBE......good stuff!
