The thickness doesn't really matter down where I live. If I pour 5 weight vs 15 weight, I can't tell a difference. In the north, a thinner oil might be worth it.
It only matters that you buy good, name brand oil. It doesn't have to cost a fortune though.

There's something fishy going on. I put 200K on a 92 Grand Caravan using 5W30 Havoline oil and it still looked like new inside the engine (I had to replace the oil pan gasket at 190K).

I used to run Havoline in my 85 MonteSS before switching to Mobil1, and my engine was spotless. Not sure if they changed their formula since then though. I have a feeling that the "tech" was trying to sell you an oil flush or something like that...that kind of sludge doesn't happen on a maintained engine unless you're using Crisco oil lol.
