Those peeps in here are just trying to help you but you don't listen.When Lucas starts foaming up in your engine and transmission the lubrication is going to be down and less effective shortening the life of your car.Why use additives if your car doesn't need them.The ONLY thing that is good as preventive maintenance is OIL itself.Every car manufacturer says they are NOT good for your car and you are listening to bull*** on the Lucas website.What do you expect Lucas to say about their own product?Read the damn car manual.Every time your driving remember that you have a white thing instead of oil lubricating your transmission and and by the way those additives have a tendency of clogging filters too..Good luck.

What I found out from people here so far is that switching to synthetic is bad/pointless if there isn't a fresh start. That's BS.

Also I've seen those bob the oil guy tests long ago, and not sure how accurate they really are. It's funny how every single mechanic I've talked to recommends using Lucas products.

Let's just that they really are a gimmick and don't work, surely Lucas wouldn't make something that is going to do the reverse and shorten the life of my cars components.

Car feels smooth so far and I have noticed the tranny shifts to be smoother, especially 2 to 3 and 3 to 4 I don't even feel/notice when it happens.

I appriciate everyones help/advice here.

Buddy,i sell cars for a living and you are right about mechanics at least.My mechanic does the same thing,tells the customers that Lucas and every other BS brand out there is good for (engines,transmission,tires,brakes,mirrors and what have you).Why?So every one that goes there wants the additives put in and they make more money like that than just plain oil change.No mechanic will put that ****** in their cars rest assured.There is no point discusing this anymore though.

None of these people sell the product. One of the mechanics is someone my dad has been going to for almost 20 years.

Very old thread, but I was looking at your profile and noticed you had your transmission rebuilt. I was wondering if using the wrong fluid (anything other than Toyota T-IV or Mobil 3309, which are the same) led to your transmission's demise? In the beginning of this thread, you mentioned you had used Castrol Import ATF, which isn't compatible with the U140E transmission.

Hey most like it was the use of the wrong fluid and not changing the fluid often enough. I'm sure if I used a synthetic ATF fluid and drained and filled every 50,000 km it would of not broken apart.

Good luck on your car

I would never add any kind of additives to synthetic oil. You'll likely just louse it up.
