Renault 1.6 16v - K4M

[AnteLo]

Hello everyone,

I have a Renault with a 1.6 16v 107hp k4m engine.

Last 5 oil changes I've put ELF FT 5w40 A3/B4 full synthetic rn700/rn710, it's harder and harder to find that oil and it seems like it's out of production.

I'n in a warm climate (never gets under -5°C) and the car is used for daily/spirted driving with OCI of a 7000km ish.

Since the engine doesn't have an oil cooler and the coolant radiator fan turns on when the engine reaches 100c, would it be smarter to put 5w50 oil in it?

what are the thoughts on Motul 8100 X-Cess Gen2? Mobil 1 FS x1 5w50?

engine is not tired but by nature from factory has "low" oil pressure and since I'm going to compete in longer racing events I'm looking for cheap-ish oil that I can also race on.

Thank everyone in the advance,
Ante

You have different options for RN0700/710, in worst case some A3/B4 MB 229.3/5 is perfect. Depend on use you could use 5w50, but I won't do it if you have cheap 10w40 and 5w40 for short OCI.

These three Castrol EDGE Euro oils cover Renault RN0700 / RN0710 that your engine requires.
Castrol EDGE Euro 0W-30 A3/B4
Castrol EDGE Euro 0W-40 A3/B4
Castrol EDGE Euro 5W-40 A3/B4

Mobil 1 FS Euro 5W-40 covers RN0700 / RN0710 too.

Motul 8100 X-Cess 5W-40 Gen2 also covers RN0700 / RN0710 as well.

All these oils will be great for your engine. Your engine is also 5W-30 spec which should be A3/B4 too. I don't think you need 50 grade oil.
