I dumped some of the lucass magic oil in the tank. It took a few miles but now it's mixed in well and a definite difference is felt . Of idle it would have some jerking (torque spikes)and u could hear some pinging . Cant hear it no more ...and finally of idle accel is smooth. 87 octane is definitely not good for our cars . The spark advance is too much and possibly running lean also. So my advice if ur going with low octane pour some octane booster the fuel spark curve will work much better. And yes its bone stock

I like Lucas products but I ran mine with 87 all the time and no issues. I think it's more likely you got a tank of bad gas..
I would be getting bad gas for the last 5k miles in that case ? I tell u its either lucas or high octane for from now on ... rather use lucas though
