OK! It's now 8 days later and I'm almost at the end of the tank of gas(waiting for the "Low Fuel" light to appear. And only now is the engine just starting to feel like it's waking up as this lethargic feeling that I was experiencing is why I threw in a large bottle of cleaner. Lethargic/lazy is how I will describe the Lexus RX-300 V6 engine. Used to be ballsey now, it just goes about it's business. It's smooth with no hesitation, just not quick as it was. Quick and snappy actually is how it used to be. Even lost about a second on the 0-60 mph by my timer(same one used when new). My fastest 0-60 best was 8.6 seconds, now I lucky to get under 10sec's. Same road, same digital timer, usually measure with 1/4 tank of gas for consistancy. Seat of the pants is what I noticed first which is why I retested. Cool temps or warm it doesn't matter. Vehcile is well maintained. Plugs look great, the way I want plugs to look!
My question is, can I throw in another bottle on this same OCI? Seems like another bottle might do the trick. Changed the oil/filter late June, barley gone a 1,000 miles! Oil/Filter are: 2qts QSTP 10W30 3qts PYB 5W30 and Puro Classic filter.
