Been using Toyota 5W40 full synthetic since day 1 when i get my Vios dugong. My fuel mileage remains the same till now 2020 no change which is about 450KM.

It's always a good idea to stick to the manufacturer recommendation because the specific oil is tested for specific engine that it will not harm/ disintegrate the seal/ gaskets/ O-ring whatever inside your engine system. Certain old cars cannot use full synthetic oil not because of the piston tolerance or whether it's a thicker or thinner oil, it's simply because the newer oil might damage the seal causing leakage.

My car comes close to 10 years and still going strong. smooth ride and no drop in mileage. I do EO change every 10Km sharp.

I recently found out sellers are selling dirt cheap Toyota 5W40 engine oil in Shopee, and i'm not sure if those are fake. Toyota dealers sell at RM160++ minimum and they sell almost half of dealer price.

Has anyone ever purchased Toyota EO from Shopee/ Lazada with super cheap price? Any comment/ observation? Any constructive answers would help to make an informed decision for potentials buyers in the forum. I myself always get the spares from Toyota dealer like ST AUTO SPARES or VANLI to be safe but pay a little higher. Also can anyone share if Malaysia Toyota oil is manufactured locally or import? Could that be parallel import? I saw what's written on the label is "Buatan Malaysia" even the cheap one sold in Shopee/Lazada so i doubt it's parallel import most probably fake.

THX.

I will certainly consider all the valuable feedback above. Thank you.
Nowadays many workshops and online merchant selling fake oil so I must learn to be a little more vigilant.. a bit of kiasi attitude.

I have checked the online merchants and wow real cheap vs Toyota oil.
Now my next step would be how to identify fake oils.... i recognize fake oils are rampant those unethical sellers reaping super high profit causing pain in buyers arse.

I saw many many comments maybe i should look for some trusted sellers now instead.
