I used it for about 6 months and around 6000 km on a Diesel Toyota Yaris 2013 d4d (Euro 5 with DPF) without any issues, but then it became apparent during cold starts that there were definitely more vibrations, so I changed it with a similar one from another brand and the cold start improved again. Around 6000 km, in my opinion, it needs to be changed. The oil specs are very good. It didn't burn any oil. It contributes to fuel economy. Finally, I would like to mention that I have the feeling that some people mistakenly choose C3 oils over C2 oils, thinking that they are "better" than C2. The only difference between the two categories is the HTHS, which of course should be considered in addition to the viscosity, for example, 5w30, and the TYPE of oil recommended by the manufacturer for the specific engine (refer to the car's manual), in this case ACEA "C2" (Toyota Yaris 1.4 D4D (2011-2014) 1ND-TV)

Excellent oil for Citroen C4 diesel, slightly reduced consumption and reduced noise compared to the equivalent Motul oil I had before, I have been using it for the second year now!

I started using this specific oil in my C4 1.6 e-hdi after 100,000km. I noticed a CLEAR difference in fuel consumption of about 5-10%. But what impressed me the most was the REDUCTION IN NOISE. No comparison to any oil I had used before (Total, Yacco mainly). I believe it is the best 5w-30 for the specifications of PSA and others. Needless to say, I will continue with the same.
