Query: Keeps vehicles like new ...

I was just checking the price of Lucas @ Amazon.You can get it locally at Salvo.Lucas oil treatment will rejuvenate seals.I used it in a 10 year old JD tractor.It ceased leaking due to its viscosity.I am going to change gasket, but when you're busy.Lucas transmission treatment will make shifting smoother.I used it in 95 Mazda B2300 where manual shifts were sticky.The vehicle was well maintained, meaning very good condition.The transmission felt like new after its fluid change.Talk about molasses ... LOLPer this product, the objective is not to get better gas mileage.It's to keep the engine clean.You want better mileage, ride a bike.Common sense says you are restrained by the HW you are using.I would rather use a product that works after oil changes than tear an engine apart to fix fuel issues.
