Hi sifus,

I'm considering BOLD eo for my 10 years saga flx with 250,000 mileage. I have been sending my car to SC for service all this time. They use semi syn 10w30 eo for my car. Now that I 've bought new car, I'm thinking of buying eo online and service outside for my saga. I will be using saga as my daily drive to work.

Is BOLD oil alright for my usage. If ok, should i go fully syn since its cheap or maintain with semi syn. They also have high mileage oil 15w50, should i use this instead?

Thanks for any input

I would suggest buy 5w30 fully synthetic. Buy via Lazada official brand shops since there are many fake EOs.
Example Mizu at Lazada

10w30 is for heavy loaded commercial vehicles like trucks:

But usually new car ppl will go back SC la, else will void warranty later (engine or other car hardware if suddenly spoil, you wanna pay yourself if still warranty?). Ask your SC how many more years warranty? Then just follow service at SC until your car warranty no more.

Yes, the new car will service at SC. Saga will service outside. If before this saga use 10w30 can change to fully syn no problem? Considering Mizu also but Bold is cheaper. If perform the same, i would prefer cheaper option
