This car has serve me well as far as the motor and trans ...

I thought mine was guzzling oil! Not so, it was sucking it out the hose from the valve cover to the elbow in the air cleaner hose to the throttle body!

So far no further need to add oil every 300 miles!

I would avoid "miracle" additives. Maybe change to dino oil or a different brand. GM claims 1 qt/1000 miles is OK.

Well a little up date when I put that restore product in my oil change fresh a week ago and know my oil light came on and then restarted it came on then the light goes off and stays off ... so I'm like wtf is it possiable that this stuff messing with the sensor ? I know it hard to tell over the internet just any help at all

That is pretty wild... Possibly your additive might have cleaned off the sensors enough to make it begin sensing it correctly?
I also had a revelation. Of course, I don't know the past history of the type of driving on this car, except for the oil change, tune up, safety/service records on Carfax. But after I sprayed Gumout Choke Cleaner the air intake, PCV and each spark plug, the idle was very smooth, and the accellaration was impressively clean sounding, compared to before I did it.

That is for older carburetor cars, could damage the sensors and throttle body. Next time use throttle body cleaner

Do you have a suggested Throttle Body Cleaner, and do you know if that product will clean the intake and spark plugs like Gumout will? I've found Chemtool and Gumout work amazingly, and it was even recommened by a master mechanic I know who works exclusively on GM light duty and utility trucks contracted for the state. Thanks for any advice.

These are a great kit and sensor safe








Also great for the SS DI intake valves
