I used to own a 1992 Dodge Grand Caravan, which was used when I bought it in 2005 and had about 115, 000 miles on it. I changed the oil in it and ran the Lucas Heavy Duty Oil Stabilizer in it every time I did an oil change. I also used every fuel up Lucas Fuel Treatment. They both worked well because up till the van was totaled in an accident, I had it over 220,000 miles or so. But the best of your products and the two I always recommend to everyone is the Lucas Power Steering Stop Leak, Lucas Transmission Fix. Reason being for both. The Lucas Transmission Fix was used when I changed my transmission filter, and fluid. Little did I know that in Dodge Transmission that I should have used the ATF +3 not regular ATF. The mechanic I worked for told me to get that out of the transmission instantly and replace it with the correct fluid, I did so and ran another bottle of Lucas Transmission Fix in it. I didn't have any transmission problems at all and it shifted fine up till the accident. Now for the Lucas Power Steering Stop Leak. My rack started to leak and I was sick of buying bottles of regular fluid. I didn't have the money to replace the rack, so knowing about Lucas products, I looked for something to help me out. I came across the Lucas Power Steering Stop Leak. I must say, no it didn't stop the leak, my rack was way far gone for any product short of a hole filler stopping the leaks. But what it did, even with the whole power steering reservoir empty, it kept that vans steering perfect, never lost any power with it and not a bit of noise, and trust me, without the Lucas Power Steering Stop Leak in it, it made noise like crazy. I can say, that the Lucas Power Steering Stop Leak even with an empty res can keep your power steering system working well, I know because it worked great for me. I tell anyone who is changing the fluids in their car to add in Lucas products, and if they have power steering noises or leaks to get the Lucas Power Steering Stop Leak. Great product. 100% satisfied repeat customer.
