My KIA Ceed recoomends for manual transmission oil: 70W API GL-4. I cant find nowhere 70w oil, so can I use 75w oil (api GL4) instead?

It's not cheap, but it's 70W:

Highly rec. NOT exceeding mfr's rec'd SAE weight recommendation. Do you REALLY want gravelly-feeling shifts particularly when cold? That might happen.

Necessary cold weather performance depends upon your ambient operating temperature.

There are plenty of 70W or 70W-75W dual rated products out there you'll probably have to buy it online since it's a European vehicle I don't know what retailer to recommend since I'm stateside , if it specs a GL-4 lube don't use a GL-5 gear lube as it can cause damage to brass parts.

Here’s a 70W MTL:

Does Kia not offer a fluid that meets their own specs? That occasionally happens.

I just went through this fiasco wondering why I couldn't use 75w90 gear oil vs the 75w80 my manual tranny calls for. Molakule should chime in here but you really need to stay with a GL4. I ended up buying redline MTL which is a 75w80 and is made for manual transmissions.

As long as its GL4 in the 70-80 range it should be fine. I think many forget the ratings on oil are a range not an exact number. I have seen many 75s that perform as well or better in cold weather than a 70.


yup

Totally agree. 70W is a range of viscosities... and even there are wide differences in the 40 degree C behaviours... and in the Brookfield Viscosity behaviours, and in the Viscosity Indexes... all within the same basic SAE oil "weight".

Any full synthetic reputable name 75w GL-4 will be just fine.

It's still good to look at the stats for cold flow if they can be found for any oil.

Yes, you can and you get stronger oil film for components protection .
But you might have higher tendency of encountering morning cold shift harshness ,depending on your locality .

I don't think '5W' is really going to make that much cold difference where the OP lives.
