I am currently using 15w40 mineral shell engine oil for my car . The car is abit sluggish . What is the suitable engine oil ? I think my car is in good condition , coz the previous owner kept well of the car . It's actually my neighbour 's car . So , i know about it

changing engine oil will not help much. if you want use semi synthetic or fully synthetic engine oil with 10/40 rating.

i am currently using mineral oil 15w40 now . changing to semi synthetic would help to restore the power loss ?

You can try to go for 5W30 oil. This is lighter oil which is also suitable for your Honda.

will it be too thin ? since the car is quite old , it's 2004 car . But , I think it's in good condition , no oil leak and oil loss

how much mileage have your honda accumulate? tried flushing the engine before?

Don't be a cheapskate use semi synthetic at least :-)

140k stock mileage , havent try flushing engine before

Should be fine. I didn't recommend you to use 0W20

any brand suggestion ?

Anyone heard of ELF ? is it as good as Total ?

Recommend you to use Honda Semi Synthetic oil.. I think it's weight is 5W30 (blue bottle).

is it possible to get semi synthetic oil under rm120 ? any suggestion ?

Why did u use 15w40? If u follow the honda manual it states at least a minimum 5w30.
Therefore changing to 10w30 will restore the engine performance. It will improve the FC alot also.
idsi engine dont need such heavy oil even at such mileage.
The engine operating temperature isnt that hot either.

Fyi my family owns the IDSI since new and still send back to Honda SC for service. They also use Honda 10w30.

ok , thanks for the info

U can try use Castrol Magnatec Start-Stop 10w30..straight away notice less noise from engine..using this oil right now compared to Castrol Magnatec 10w40.

this ok ? https://www.lazada.com.my/products/bosch-sn...za3g9P&search=1

I'm wondering if using thick engine oil (in my case i use 15w40 ) will harm the engine ? If tt's ok , then i plan to use until 5k km then i only change to 10w30 semi-sythetic

For emergency use ok..but not recommended.Make sure u change it on time coz mineral oil create much sludge compared to synthetic oil based.Thats my personal opinion based on watching review on youtube.

Last time i use castrol 20w50 mineral oil for my saga , the car feel sluggish , after changing to shell 20w50 and nasa 20w50 , the car is abit lighter . I'm not confident with Castrol
