Hi.
I bought a second hand car. It has 56, 000 Km mileage. I just changed the oil with full synthetic Repsol 5W-50 (Carrera) viscosity. I researched on the internet that it's too thick and will cause issues (leaks, etc). I live in South East Asia, tropical climate (28 to 34 degrees Celsius). I drive around 10-12 Km a day with heavy traffic during daytime but I go home at night (no traffic). I went to the mechanic who replaced the oil and told me that it's ok. I'm starting to doubt now based on what I read.
The previous owner changed mobile phone number I think because his number couldn't be contacted anymore. He did mention before that he only used fully synthetic oil. Car is in good condition when I bought it. I'm worried now. Should I just replace it with lower viscosity ASAP? In the manual, I found 10W-40, 10W-50, 15W-50. There are lower viscosity too like 10W-30 in the manual. Is changing to lower viscosity after few days of using higher viscosity bad? Or should I just wait for 5 more months and change the oil with 10W-40?
I used Repsol 5W-50 because it's the only oil that I found in the mechanic shop with API-SM. The rest that are 10W-40 and 5W-30 are API-SN. I read that API-SN is compatible with old cars. Is this true as well?
Thanks.
