Yes and yes and yes.
Depending on how much Honda charges for oil changes you might want to 1. let them do it. ($25. per 5,000 mile OCI is what my local dealer charges, of which normal charge for labor is 18 dollars=7. for consumables) Or you might want to 2. BYOO or bring your own oil and let them do it. It would be very hard for the dealer to match a .49-.65 cent per quart price 1.67-2.21.(normally 1.50-1.99 per quart) 3. DIY, which would cost oil and filter between $2.07-6 for filter plus $1.67- 6.80 for oil = $3.74-12.80. CONVENTIONAL.
After the first oem 5w20 conventional fill and 10,000 mile Honda recommended OCI, I personally went to DIY with $2.07 WM SuperTech 7317 filter and 3.4 quarts of Mobil One 0w20 @$4 per qt=13.60+2.07= $15.67. This obviously costs MORE!!! (than the above paragraphs conventional examples) HOWEVER, over 2 each 10,000 mile intervals, I found mpg went up with synthetic over the conventional oil; a range of .5-3 mpg. The average seem to be 2 mpg.
So if you do the math with 2 mpg saved over 10,000 miles savings of: $32.34 Again DIY a range of 3.74-12.80 PLUS 32.34 $36.08-45.14 conventional vs $15.67 synthetic.
(It also should be fairly obvious if you change at 5,000 mile OCI's the costs will be double or 7.48-25.60 plus 32.34 39.82-57.94 vs 15.67 synthetic)
(avg of 37 mpg-35 mpg/10,000=15.4 gals SAVED x current price of unleaded reg (2.10 here)=$32.34. This translates to 570 MORE miles.
It might surprise you to note that running synthetic oil is cheaper!! (- a lot due to fuel savings!! )
and uses WAY less resources. (15.7 gals of fuel LESS (-5.4%) and up to 50% less oil products)
Mobil One currently comes in 5w20. I am told Mobil is bringing the 0w20 back to market sometime in 2006.
The only thing bad about the following list of conventional 5w20 oils that are good for our Honda's, might be the ones I inadvertently leave off. So as a observation, I would buy the 5w20 on PRICE and/or coupons. Life is good at .49/.65 per quart, eh? Compare the 5 quart jug prices also. If I had decided to stay with convention oil, Superflo would be my choice.
Havoline
Chevron
ExxonMobil Superflo, (aka oem)
Honda 5w20
Mobil Drive Clean, etc.
