Hi,
I used to use Ryco Z87A for my 92 ES300. But got myself talked into using Filtercraft by
a mechanic who says it is better than Ryco and that it's made-in-Japan.
I tried google but didn't get much information, which now leaves me regretting my decision to use Filtercraft.
Has anyone used it or have any information about this product? I just hope it doesn't spoil the engine.
Thanks
