VALVOLINE Engine oil

I'm using "Valvoline Modern Engine Oil" since they have patents and claim to have some chemistry there to keep the valve stems more carbon-free.

Pros: carbon-free valve stems

Shell Engine oil

Walmart. Shell Rotella 5qt for $20. Or Mobil1 for less than $25 if they're out of the Shell and K&N filters always in stock.

Pros: good price, always stocked

I always use VR1 (Valvoline) 20w50. Excellent oil. The car runs beautifully on it and has had no issues.

Pros: excellent oil, no issues
