sorry. i'm a newbie car owner. Can someone please explain to me the different grades of engine oil and their comparision? eg. 5w30, 5w40...
I read on mycarforum that a mechanic in thomson charges oil change labour for $15 only. includes basic fluids topup and air-con filter cleaning. Just bring your own oil and oil filter.. in recession times like this... must save... haha :)
I'm driving a Honda Crossroad.. so which grade of engine oil is more suitable? Thanks! :)
look at your car manual. it should state.
Most places charge at $10 for labour if you bring your own oil n filter.
Basic fluids like wiper water, battery water, brake fluids etc you can also top up yourself
And a Xroad is still quite new on roads, so I don't think you need to top up batt water, brake fluids, radiator etc ..
The Society of Automotive Engineers, usually abbreviated as SAE, has established a numerical code system for grading motor oils according to their kinematic viscosity. SAE viscosity gradings include the following: 0, 5, 10, 15, 20, 25, 30, 40, 50 or 60. Some of the numbers can be suffixed with the letter W, designating their "winter" or cold-start viscosity, at lower temperature.
Viscosity is graded by measuring the time it takes for a standard amount of oil to flow through a standard orifice, at standard temperature. The longer it takes, the higher the viscosity, and thus higher SAE code.
Note that the SAE operate a separate viscosity rating system for transmission oils which should not be confused with engine oil viscosity. The higher numbers of a transmission oil (eg 75W-140) do not mean that it is necessarily higher viscosity than an engine oil.
Spend some time searching the net and you will get to find out what you want and credits to wiki on the above info
I read today sunday time they do teach us DIY(HOW TO CHNAGE ENGINE OIL)
Ypu should change your car's motor engine oil and oil filter every 5,000KM or every 3 mths..Getting a mechanic to do it would cost $60-$200, so leran to do it yourself...
What to do:
1)Locate the oil drain plug under your car.
Place a container under the plug to collect old engine oil.
2)TURN PLUG COUNTER-CLOCKWISE WITH A WRENCH TO REMOVE IT.
Be ready to grab the plug as it comes loose.
3)Allow the oil to drain completely into the container.Check the sealing washer on the plug before re-installing it.If thw washer is worn or broken, get a new one.
3)Remove the cap from oil the oil filter hole at the top of your engine.This is
usually located around the oil pan of the engine.Unscrew the oil filter by turning it counter-clockwise with large locking wrench.
After remove the oil filter, empty the oil into oil drain and container.Always wear protection glove and eye wear.
4)Open a new bottle of motor oil.With your finger, apply a thin layer of oil on the new filter's gasket.Install the new filter by turning it clockwise with both hand, until tight.
5)Add engine oil (above)to the oil fill port which is usually located on the valve corner of
the engine.Most car and light truck will require 4 - 5 quarts of motor oil.
6)To check the engine oil level, replace the fill cap and let the engine run for one minutes, then turn it off and let the car stand for 2 minutes.
7)REmove the oil dipstick level indicator to inspect the oil level.Make sure the oil level is between the specified lines on the indicator or add as needed.
8)USED engine oil is classified as a toxic industrial waste under the environmemental public health regualtions and must be taken to licensed industrial waste collectors for proper recycling or disposal
.Check the list of licensed toxic on NEA websites :

TS asked for the engine oil grading and what they mean, not how to change oil..
yup...you are right...overlook on that....
correct me if im wrong. the different grades are just there to suit different tastes. generally, a 5w30 is thinner than a 5w40. a thinner oil is easier to flow/pump and mostly by people who bring their car for track days. a common grade is 5w40. most shops that i've been to carry this grade the most.
Yours is a new car? then use 0w30.
thinner oil gives you better fuel economy. Your car manual will show the recommended engine oil type to use.
I carry amsoil and let me explain using this example
ex - Amsoil 0w30, 5w30 & 10w30 synthetic oil are all 30 weight oils. W means winter. In winter weather, the respective ow,5w and 10w flow accordingly when the engine warms up. It is important that one must understand the numerical values given to these various weight oils are strictly empirical numbers. Ex, 0W doesn't mean that the oil has no weight.
Ex - Amsoil lubricants
Amosil ow30 is 57.3 cST @40 degree celsius @ 11.3 cST @100 degree celcius, 5w30 is 59.5 cST @40 degree celsius @ 11.7cST @100 degree celcius & 10w30 is 66.1 cST @40 degree celsius @ 11.7cST @100 degree celcius
One can see the kinematic viscosities are extremely close. Thus, you would be hard-pressed to detect these differences on initial engine start up w/o specialised engine test equipment.
Is 0w30 too thin a viscosity for high ambient temperature operation? NO! Thicker viscosity oil are not always better since in addition to its various engine lubrication functions, an oil must alsoeffectively transfer heat. Only 60% of an engine cooling is performed by the engine coolant, and only on the upper half of the engine. The remaining 40% of an engine cooling is performed mainly by engine oil.
How to read an engine oil label
Detailed information about the quality of your engine oil is contained in the API Service Symbol, or "Donut" usually found on the back label of high quality oils.
In the centre of the donut is the SAE viscosity grade (for example, SAE 5W-30). Viscosity is a measure of the oil's flow characteristics at certain temperatures. The first number / letter combination (e.g. 5W) indicates how well the oil will flow to lubricate critical engine parts at low temperatures. The lower this number, the more easily the oil will help your engine to start in cold weather.
But bear in mind Singapore is so hot, so " W " is not important. Only in cold countries which has winter need to worry about cold start.
The second number (e.g. 30) indicates the oil's ability to lubricate the engine at high temperature. In this case, the higher the number the thicker the oil. A multi-grade oil, SAE 5W-30 in this example, satisfies the requirements of both cold start and high temperature viscosity grades.
i would recommend 5w30 to you. My buddy on crossroad is using 5w30. You can use 0w20 if you re light footed driver. W40 - when you hit about 100k km. I am still on 0w30 at 105k km. W50 is not meant for your made.
