Synthetic or Coventional?

check this out, posted yesterday on the mechanical maintenance side of the forum:

This is probably the opposite side of the operating spectrum- very cold in Vancouver, I imagine. The OP states his mechanic used dino and mostly fram filters for the first 110,000 miles.

This cuts the price in half compared to 5000 mile dino OC's. This also means one less filter to buy, and one less OC you have to do. RP rocks!


On what motor?

I love this question. That's because my answer is always: try a blend, lol.

Not as cold as some would think...it has a marine climate similar to Seattle & Portland. Just for the record, December & January are the coldest months with average LOWS of 1 C./34 F.

It was the warmest city to ever host the winter Olympic Games.

heres how i look at it (i usually buy filer/oil in a deal) the average 5qt Valvoline conventional/stp filter deal here is $17, yet i could get (example) (advance current deal) 5qts synpwr/p1 for $27 so even if i only doubled a 3k oci and took it to 6k im still saving money

Correct. Somehow, though, RP get unmercifully bashed here, while Mobil 1 Extended Performance etc. does not. Syns are no more expensive than dino's, except to the math challenged.

Pretty much any one that is out of warranty.

I "follow the book" until then though because I would never want a hassle with a dealership.
