I currently got a d15z1 motor with 200,000 plus miles on it and wondering if its good
to use this. i dont know how much to put in says to put
1 quart lucas and 4 quarts oil.

but my engine takes only 3 1/2.
so do i only put 1/2 of lucas and regular engine oil?

what positive benefits do i get when i use this and negatives, my engine is still strong.
i rev the **** out of it and will it give more power?

PLUS - if i use it once do i need to always use it for future oil changes>???

 

waht ever floats your boat....

you might notice a little differences, but not alot...it's really up to you, it wouldn't do the engine no harm if you stop using it

 

DONT DO IT!!! i did it to my D16Y7 and blew my motor, the oil went all they way to the head and the bottom dried resulting in the death of my motor.

 

Seriously?
how many quarts did u put, also anyone else had experienced with this thing??

 

You clearly did something wrong, I and many other peole have used this and it works fine.
I Have used it many many times in my d16y7 with over 200k on the clock and it continues to run perfectly.

 

lol! ppl hav been using lucas for ages...it wasnt lucas' falt

 

seriously. leave poor george alone
