Engine oil (Havoline)

[mirzataha3]

Hi! I have a toyota Corolla 1.8 Altis automatic 2010 model, it is 80k driven. I want to change it’s oil and want to switch to fully synthetic. I like Havoline 5w 30 fully synthetic and this grade is also recommended for this car. I live in karachi so just wanted to get your opinions that should go for it or suggest me any other oil?

I am using same oil in my corolla and satisfied. Go for it.

Just make sure to buy from authentic company operated havoline outlet to avoid counterfeit oil.

Caltex flagship store. Caltex is selling havoline products directly at daraz. Pk

Acha which one should i go for
-5w-30
Or
-5w-40

[saqibhassan95]

Just continue it
5w30 is fine

[ahmedstudio]

5W30 is the grade for this engine

[mirzataha3]

I hope it won’t cause any leaks or oil level drop?

[ahmedstudio]

If engine is not week, it won't

[mirzataha3]

Ohhk thanks man! It is original btw.

Go for 5w30, if its start reducing oil then you can go for 5w40. Hopefully it will not.

Go for 5w30, if its start reducing oil then you can go for 5w40. Hopefully it will not

Oils with same base viscosity have usually same noack volatility
So there's will be no difference in 5w30 vs 5w40 consumption

after how much interval Havoline 10W30 SN (Mineral) should be drain so that to be on the safer side?

[mirzataha3]

Since I am going from mineral to fully synthetic so should I flush the engine? If yes then which engine flush should I use?

[saqibhassan95]

so should I flush the engine?

not required, fully synthetic oil itself will do the same in 1-2 next changes

[mirzataha3]

Ok

[ahmedstudio]

No need of flushing. Synthetic oil takes care of it
