I ask this question because the 5w20 am seeing are not from reliable brand and mobil Nigeria did not have 5w20. pls auto guru in the house assist a brother for better performance of the engine.

waiting for auto gurus

Try and stick to manufacturers recommended oils and fluids and your car will last very long.

Who said Mobil 1 does not come in 5W20? That is exactly what I uses in my Honda. If you are in Lagos, please contact Gazzuzz. PS: Please kindly obey manufacturer recommend oil

Always stick to what the manufacturers say and stick also to the time frame they gave in Oil change.

When sticking with manufacturer recommendation of very low viscosity grade of oils like this, ensure you stick with VERY TOP QUALITY FULL SYNTHETIC oils.

Else, use 5W30 Synthetic especially if you drive under high speed and load.

Aisin is a reliable brand! You can check on google

Nothing is wrong. 5w30 is a little bit thicker than 5w20, they are both thin synthetic oils compared to 20w50. In fact it might even be an advantage for high mileage cars so the oil won't be too thin at high temperature.

There is very little difference between both grades of engine oils. 5w30 should serve you better in a car that was built 12 years ago.

On point.

Let me see, at what point is ur car Engine more vulnerable to oil dispensation? when your car is at high temperature or B4 it starts?

PS{Your answer will make it clearer the reason we use manufacturer specific OIL.

Use 5w30 from a reliable oil brand and service as indicated on the owner's manual. Congratulations on your new car!

I don't understand ur question, but I know both oils have same weight when cold. 5w30 is slightly thicker when hot. If 5w20 is not available there is absolutely nothing wrong in using 5w30. And for a high mileage car 5w30 will offer better protection depending on the condition of the engine. Even some manufacturers that recommend 5w20 still recommend 5w30 if car is old and will be driven in temperate regions most of the times.

ok in fluid dynamics, heavy Oil flows slower than light Oils at same pressure right?
ok the car Engine is most vulnerable to friction at startup cos all Oils are at the Sump and it relies on the Oil pump to send the Oil up asap when the Engine turns(this is where wear and tear takes place the most no OIL)
Now at startup you use a heavier Oil what do you think will be happening every morning you start your car??

No you can't. The last digit is most important in our region.

This is where u get it wrong. 5w20 and 5w30 have the same viscosity when cold, but 5w20 thins out faster at hot temperature. Nothing wrong in using 5w30 in an engine that requires 5w20. The little bit of thickness u gain when hot privides better protection especially in high mileage cars. But using 5w20 in an engine that requires 5w30 is not advisable.

Now you lost me, the viscosity is the weight one is W20 the other is W30 , so you are telling me something that weighs 20 is the same as 30 seriously? please tell me you are joking. Your Engine bores for water and Oils are friction proof stays the same dimension unless ur Engine fails. Look if ur Engine cost N80k you can even run it with cooking Oil but if It will set you back N500k to 1m, you might just want to stick with what the book says.

Oga stop confusing ursef. The weight at cold temperature is the number before the W, in this case '5' while weight at hot temperature is the number after the W. The only advantage u get by using 5w20 is a slight improvement in fuel economy which can be negligible as car gets older, but u are getting better protection. With 5w30. Also 5w30 will not cause sludge or any damage to an engine that requires 5w20. But when u reverse it then we might have a case as u don't want to use a thinner oil when manufacturer recommend a thicker one at hot temperature.

As for me I will take the better protection over negligible fuel economy if my car is over 12 yrs

Bross no problem no need to drag am since U sabi pass the manufacturers we will leave it there, for me my RRS says 5W20, I'm using that till the car dies.If ur car says 5W20 U can us 5w30 in urs.I rest my case.

Cartalk get characters sha.

Bros no be fight. Do ur research u will see both oils have the same viscosity at low temperature. Like u said, friction occurs at startup, since both oils have same viscosity at this temperature then u agree it makes no difference. I understand the need to stick to manufacturer's specs though.

If manufacturer recommends 5w30 then I wouldn't put 5w20 in my engine because they have a reason for wanting a slightly thicker oil at hot temperature. Using 5w20 in this case might be too thin for the seals.

I tell people all the time to follow the manufacture advice all the time.. If the manual says 5w30 in all weather, why use 5w20 or anything else... this is one of the reason I stay away from naija use cars ...

Here we go again.

You can use your 5w30.. Nothing wrong with using 5w30..

Follow greenhulks advice. You will be okay. At startup, both oils offer the same protection. At higher temp, you may lose a bit of mpg as the 30 weight oil is slightly heavier but in an older car is not a death sentence. Buy synthetic to keep sludge at bay.
