Thinner oil gives less friction, hence improves fuel economy.
Blame for this one goes to the feds...they said "make your cars get better fuel economy right now," and everyone said "okay, run thinner oil in them and you'll GET better fuel economy."AnswerI can't specifically explain it for an Accord. All I can offer is that there seems to be a trend by manufacturers to specify lower viscosity oils. E.g. My 1988 VW Golf recommended using 20W50 in the summer, if not straight 40 weight. My 1988 VW Golf recommended 10w30 or 10w40 in the winter. That makes sense to me: "thicker" oil when the outside temperature is hot. The normal service recommended oil change interval was 7500 miles. Engine lasted ~230,000 miles with only slight oil burning at the end.
My 1997 Ford Escort recommends 5w30, year round. When I first saw this, I found it hard to believe: Ford is saying use the same weight oil during the summer in Arizona where the ambient temperature might be 110 F, and the exact same oil in the winter in Maine when it might be -20 F? BTW the normal service recommended oil change interval is 5000 miles. At 150,000 miles, the engine is burning about 1/2 qt. of oil every 4000 miles.
Now my 2003 Mazda MPV, with a Ford engine in it, recommends 5w20. I do have concerns about engine durability/lifetime with the lower viscosity oils.
If any oil/engine guru can explain the reasons and justifications for these changes, PLEASE do!
I read somewhere said modern engine component are tighter than before, thinner oil will make it flow faster and easier. But I do have the same concern since I live in So California which summer high will be up to 105+ and 30F in the winter. And Honda recommend 5w-20 at all time. But better follow the manufacture recommended.
Use whatever the owners manual calls for. If no manual then what?
the ryobi owners manual calls for a .095
Regular 87 is what the owners manual calls for
.035-.039" is what the owners manual calls for...
Unless it calls for premium gas in your owners manual your wasting your money using premium.
The 2002 Ford F-150 owners manual shows ( 5 W 20 engine oil ) for the 4.2 L - V6 Calls for 6 qts of oil.
Could be either green or red. Red 5 year, HOAT type is what the service manual calls for.Could be either green or red. Red 5 year, HOAT type is what the service manual calls for.
Well, if it is a Deville with the Northstar 4.6L engine, the manual calls for 7.5 quarts with filter.
Manual calls for 4.5 qts with filter change.
I believe that the ratio ought to be 25:1 Actually, the owners manual calls for 100:1 ratio. Just read this owners manual yesterday. This is assuming that the engine has the initial 10 hours breaking in accomplished, which is safe to assume, seeing as how this an 19 year old motor. I thought this was an awful lean ratio, and I plan on running 50:1 in mine.
The standard maintenence calls for : 90,000 miles if its a manual, & 100,000 miles if it is an automatic. . The maintence schedules are in your owners manual, & online as well. . Hope that helps ya. . .
Yes, if they both call for the same type. You need to use what ever type the owners manual calls for.
