I've been a long time lurker with moderate car repair experience (way more than most Americans but less than many on these boards). It fascinates me how into motor oil some people get. I understand if you're racing or something of that nature. But it flabbergasts me that someone commuting to work asks if oil X or oil Y is a better oil. Sheesh. I ran a 74 Toyota Corona Mark II for 250k on whatever filter and oil were cheapest. I ran a Nissan Pathfinder on Dino in summer and Syn in winter for 295k miles with Orange Cans of Death. Whatever was on sale. I now run an 02 Civic Si on anything from Oreillys Dino, NAPA syn, Quaker State syn, Havoline Dino, Mobil 1, etc. Whatever I can find for cheap in anything from 0w20 to 0w40 weights. Had an older Civic I'd run on leftover quarts from the lawnmower, snowblower, and cheap store brands for $1.25 per quart. NEVER have had oil issues. If it has that little starburst logo it really doesn't matter unless you're running a turbo that needs HT06 or Dexos. Some people run syn in their lawn mower? What? My lawn mower was $110. I'd only run syn if I had a half quart of syn leftover. Otherwise my lawn mower gets 10w30 and the rest gets dumped into my Civic because it won't hurt anything. Anyone running syn in a lawn mower engine needs to give me $5 and let me change their oil. My parents have two mowers I used to mow lawns with when I was young that still run. And, half the time, we wouldn't change oil after winter. Rant over. But, honestly, this website is entertaining!
