Hello everyone, I have a 2009 model 1.6 HDi 90 horsepower 308. I bought it a year ago and am about to do my first oil change. The car has 205,000 km, but the previous owner, who was a Peugeot service center in the industry, changed the oil every 5,000 miles and took good care of it. It's truly remarkable. I wanted to supply my own oil so I called him and asked. He said he had previously used 5w30 and Mobil 1 oil, but I have a few questions. When I looked on the Mobil website, they recommend Mobil 1 Esp Formula 5w30. Would there be any problems if I bought the regular Mobil 1 Esp 5w30 instead of the Formula one? Since Peugeot recommends Total, I'm also considering switching brands to Total. The Total website recommends Quartz Ineo HTC 5w30 for my car. Will the difference between the HTC and ECS in the Ineo be a significant difference for my car? I also don't know if the vehicle has a diesel particulate filter. Finally, for a vehicle with this mileage, should I stick with 5w30 or switch to 5w40? I've asked a few too many questions, but I'm inexperienced in this area. I look forward to your support and advice. alperyacan2025-02-09 01:33:24
