I heard a radio ad for NAPA synthetic, which stated only $2.99 a quart. That's certainly a lot cheaper than the ~5/quart I pay for Mobil 1 at Walmart. So how is the NAPA so cheap? The VOA shows lots of sodium. Wouldn't that cause rust to the engine, especially in rainy or humid areas? (shrug)
Please enlighten me how to get M1 or Pennzoil Platinum so cheap. (BTW this came from a different post in the VOA section.)
