I buy all my filters at the dealer, but the oil i usually get 55 gallon drum of 15-40 rotella for my machines and my trucks.Do most of you buy your filters and oil at the dealer? I bought some filters from my cat dealer today and they were actually cheaper than carquest. Is cat or oem oil better than rotella or mobil?
Myself I wouldn't buy engine oil in 45 gallon drums unless your using it up in one shot. With 45 gallon drums is too much chance of contamination. Any of the contractors I worked for bought 5 gallon pails. They bought oil when they needed it.
Stay away from the cheap filters, Fram is the worst Fleetgaurd or Luberfiner or Racor is some of the best ones.
