Because it requires a synthetic and is more expensive. OEM's that generally aren't German usually don't make it a policy to spec (expensive) synthetic oil.

Now if you're not concerned with that then yes you can use a 0W-20 and even the TGMO 0W-20 as a number of Hyundai/kia owners have with good UOA results. But be advised that TGMO is one of lightest 20 grade oils available so in your climate, since your car is not equipped with oil gauges to monitor things I'd suggest substituting a 1/2-1 quart of M1 0W-40 to give your a somewhat heavier 0W-20 oil. It will still be lighter on start-up than all 5W-20s and even most aftermarket 0W-20s, but it will retain a higher high temp' viscosity.


Why not promote the OP to find a ?w-20 oil with the appropriate builder approval. The OEM would quiver how freely it it is touted mix this with that to come up with what ?

Surely with the huge range oil of brands for selection in that grade you have in the USA, compared to OZ, there must be one on the shelf you can add with confidence in an unadulterated form straight out of the container.

Unbelievable from my view point in OZ.

Yes virtually every oil brand offers something in a 5W-20 and now the 0W-20 grade in NA but as I mentioned Hyundai/Kia don't spec' the 0W-20 grade just 5W-20.
The OP could use M1 0W-20 which Mobil states will not void any companies warranty when used when 5W-20 is specified but that's about it.
The OP inquired about using TGMO 0W-20 and is the reason for my response. If he was interested in something a bit heavier without blending, SynGard 0W-20 (220 VI, HTHSV 2.7cP) would be an option but it is not as readily available.

Caterham the vehicle in question is a 2014 under warranty it puzzles me why in this instance you promote a mix this and that to get who knows what.

If the OP is off the mark I would expect an experienced BITOGer to inform the OP to follow OEM directions.

This is my view, like you have yours, and the longer I spend on this forum I am seeing the OEMs perspective clearer and clearer.

I don't want to generalize with engines and climates I'm not familiar with.

However, here in hot and humid South Florida, thinner oils result in higher UOA wear metals, in my "fleet". Others have different results. I'm hard on things, it seems.

Whether under warranty or not is irrelevant.
For the most MPG, use any full synthetic 0w20.
You probably wont see the mpg difference when compared to a full synth 5w20.
When the transmission is due for service, use a full synth fluid there too.
