I just received my bottle of XL-18! I was shocked to see the size of the bottle and even more shocked to feel how little XL-18 is actually in it. I'm planning on adding it tomorrow. I wonder how long it takes before I will notice a difference and will I notice a difference. I will update with some results soon.
It took me about 16 miles. I Cant believe the difference. I still get a little rub here and there but no missed shifts. I have not tracked the car yet since the fluid change.
