It's been about a month now since I changed my oil and also added a bottle of STP and I just wanted to give my report on it.

- Car sounds smooth upon startup, no longer sounds like a runaway sewing machine
- Oil pressure light used to come on for a few seconds during cranking over, doesn't do that anymore
- Improved MPG, used to be lucky to get 15mpg, my average now floats between 18 and 22
- VTEC seems to be fine with it, no codes yet lol

Unsure which generation but it was in a round metal can that you needed to use a punch open can opener on.

Thought that the original foundation of STP came from Germany. Was used in aircraft to thicken oil so if hit it would give enough time for pilots to try to land their aircraft.

Your signature says ...... HK conv 5w20, STP blue bottle, PrimeGuard POF4610 filter.

HK Oil?...... what is that...... Harvest King Oil?
When was the last time your Honda was fed good oil?

Glad the STP Blue worked well for you. Maybe try STP High Mileage next?

Is there even such a thing as viscous "Synthetic Bright Stock" base oil?

I remember Andy and his STP ads. In fact I associate him most with STP. When topic came up before, some said Richard Petty more memorable. For me, it's Andy.

3-7 mpg improvement in one month, Andy and Richard would both approve. wink2
