You should change it at least every 3,000miles or every 3 months, whichever comes first. The more often you change your oil, the longer your engine will last.
Every 3000. Helps to keep the engine lasting a Long time.
(I don't believe in the long duration in-between oil changes, no matter what the oil manufacturer states.
1.Combustion gases, do pass by the piston rings in small amounts. This is Blow-by, and every engine has blow-by. (Even new engines)
When the combustion gases intermix with the oil, and chemical change happens, acids form.
These acids 'attack' the metal of the bearings,
(Crankshaft, cam, and connecting rod), plus all exposed parts inside the engine
Acids also break down the oil's viscosity, rendering it 'less slippery'.
2.Moisture is always present in the atmosphere. In the air. When an object heats up, then cools down, moisture is drawn out of the air. With an engine, moisture forms along the inside, and collects in the oil pan. Water (Moisture) and oil do not mix, and water does not have the lubrication qualities that oil has.
Metal will then touch metal, and bearing breakdown occurs.
3.Gasoline has additives in it. Although the gasoline manufacturers state that their additives, help the longevity of the engine, there is only so much an additive can do.
There is no 'miracle' additive, that will keep oil molecules from eventually breaking down.
Only regular maintenance of changing it, and the oil filter will help ensure the longevity of an engine.
[Same thing with spark plugs. Sure some are supposed to last a really long time, and SOME do, but I am a mechanic, and have been for a long time.
1.Gasoline additives build up a coating on the electrodes of the spark plug. On the side, and center electrode. This coating has an insulating quality, and the spark is not as 'hot'
The electrical spark cannot pass as easily, from center electrode to side electrode.
2.Carbon eventually forms on the bottom, of the spark plug thread area. The carbon build-up is larger in diameter, than the diameter of the spark plug thread area.
When you go to remove the spark plug this can result in difficulty, or stripping the threads off of the spark plug, and/or spark plug hole in the cylinder head.
Long lasting spark plug? Sure! Many do last very near, the spark plug manufacturers stated recommendation for replacement.
But I would remove the spark plugs, and check for carbon and additive build-up, way before the recommended time of spark plug replacement]
Acura recommends every 7,500 miles under normal conditions and you can use their schedule with confidence. My personnel recommendation is every 5,000 miles which is much shorter than Acura recommends. I recommend this schedule because I think most driver's fall into the more severe driving schedule. That is assuming you are using conventional oil. If you are using synthetic oil, then change it every 7,500 miles. Be sure and change the filter at every oil change and use a quality filter such as Purolator, or Wix. Also change the air filter every 30,000 miles. There is absolutely no benefit in changing your oil more frequently. This will only increase your cost of ownership, and create an unnecessary burden upon the environment by increasing the amount of disposed oil. The 3,000 mile oil change only puts extra profit in the oil company and mechanics pockets and is out of date on modern engines with modern lubricants.
7500 miles, but you must use oil approved for ACURA. Are you going to go by the engineers that designed and built your car or opinions on the net? 3000 mile oil changes are left over myths from the 1960's, oil has come a long way since then, so have engines.
SOURCE: Timing belt
no way timming belt should be changed honestly poor girl i know how it can be,plugs maybe but timming belts usually outlast the car itself,thats something u wait till it breaks really or around 160,000 depends on person really,i recommend from 140,000 to 180,00 they tend to loose power around there hope this helps u plz dont take it back there and definelty dont change ur belt at 70,000
SOURCE: ACURA TL SERVICE DUE SOON B1
It's a service interval reminder light that you should take your car to acura and have them perform the "b1" service. I would ask for an estimate first, and ask what that service includes. You may be surprised to find necessary and unecessary services. Some people view the b1 light as a way for Acura to get you car in there, quite possibly be charged for things you could probably do yourself.
