    Default lucas oil products?

    I have a 1996 GMC Sierra with a 5.7 L so far I have used the injector cleaner, the oil stabilizer, and the Transmission Fix i am amazed at how much difference it has made just wondered if anyone else had any stories good or bad

    I use their injector cleaner in all my cars. I switched to them a while back after a friend recommended it and I've been very happy.

    I haven't tried their other products yet... but I plan to.

    My trans was going, for about 3 months, every now and again, it would lock up but I always managed to get it to settle down and then a fter a long drive it went - I already had the Lucas in my turck stored away unopened and was going to put it but my mechanic said no.

    Well I was so far away, I put it in anyway, without draining the other stuff - the tranny unlocked, the noise went away, and I kept on driving it for another 9 more months.

    I only wished I had put it in there, when I first had a tranny problem - instead I drove it for thee more months and probably did a lot of damage in that time that would have been mitigated by the Lucas.

    The stuff works.

    Now I have a differential/axle that is about to go and wish I had done the same with that.

    As for the tranny, I switched it out with a Jasper, because it was a 460 LE, havent had a problem since and my rig is always overloaded.

    I believe in Sea Foam for everything Oil and Fuel related. Nothing beats it. However, when it comes to the transmission fluid, I changed the fluid in my pan, added new fluid and dumped a bottle of Lucas Oil Transmission fix in and it improved shifting tremendously! Almost completely eliminated the harsh 1-2 shift at slow acceleration although it still does it from time to time.
