Hi all,

Kindly need some advice/recommendation on what kinda oil to use for next service.

Next options:
- 10w30 (same viscosity as recommended by the manual), but most say it's too thin for our climate (and based on the SAE viscosity charts in the manual)
- 15w40 suitable for high mileage new engines mech says.
- 10w40, current oil but now price hike to rm131 from rm95

I don't plan to use any thinner oil than 10w30 due to an excessive blow-by problem I've been facing (Blow by redirected to OCT).

Car: 2012 Saga FLX CVT 1.3
Mileage: 90,000+ km
All bone stock OEM car.

Extra info:
- 80% Highway / 20% town.
- Rarely exceed 4k rpm / 130kph (granny foot )
- Average temp coolant (reported by Torque OBD) 89C.
- Average temp air 35C.
- Daily used.

Thanks in advance

Here is the page from the User's Manual. As stated, 10w-30 is "recommended" up to 40C and, with an average of 35C where i usually travel, that's a small margin to work with.

I know we can't literally follow this guide, but i rather not push it.

Thanks, that's good to know

Is there a rule that minerals need to be serviced every 5k km / 3 months or is that just for "extreme usage" conditions. The service book mentioned that under "normal" conditions a 10k km service is ok.
