Trying to remember but doesn't the lucas have a tendency of foaming up? I could be thinking of another product though...

Foam is not a good thing to have with the heui system.

Did you use the full synthetic lucas or the regular?

The synthetic is ok to use, but the regular stuff will foam up and make the injectors run crappy.

No good way around it except to change the oil again. Personally I don't run any oil additives, only fuel stuff.

It won't hurt anything to keep it in there, just might not run the best. I put lucas in mine when I first got it cause I didn't know better. If you don't want to change the oil again just run it and maybe change it sooner than you usually would.

What about Additives?

just a reminder of how quickly you should change your oil.

The additives in our oils keep them from getting air bubbles.
as you can see. lucas.... screws that up.
Schaefers is great oil too, and lucas is screwing it up.

By the time I get back home Talyn I'll have 10K on my Schaefers oil. I'll let you know what the lab test results are. Its starting to idle a little rough now at 7,700 miles though.
