Out of curiosity, at what point would you call it quits on a vehicle? I'm currently in a dilemma, I have a 2023 Mazda CX-50 that has been having more problems than one would expect with a 2.5 year old car and only ~38k miles. It is currently in the shop for a low oil pressure issue. TBD if its...

Just finished a holiday road trip (~700 miles one way) in my 2023 Mazda CX-50 2.5S. Heading back home on Sunday with my OBD MX+ plugged in, I’m able to monitor all sorts of different parameters on my Mazda including actual engine oil temperature, not just the estimated oil temp. While I don’t...

The EPA recently released its automotive trends report for the 2023 model year. The highlights are all vehicle mpg for the 2023 model year was 27.1mpg (319g/mi, real world), that includes BEVs and PHEVs. For MY2022 it was 26.0mpg (337g/mi, real world). Without BEVs and PHEVs the MY2023 number...

I thought some people here maybe interested in this information, so I put together my thoughts and my understanding of GPFs into this post. TLDR: Increasing criteria pollution regulation (NOx, NMOG, CO, PM) are driving the need to add particulate filters to the exhaust after-treatment systems...

Another year has gone by, that means another oil change and UOA completed on my Wife's 2015 Honda Civic. Same as last time, the OLM was showing 10% left again. The oil in the analysis is 50/50 mix of Castrol GTX FS and Supertech 10k version both 0W-20. This car is mostly short tripped, so not...

I was reading through some R&D papers that Honda releases on their website and thought people here would be interested in it. FYI, this is probably gonna be a very long post. TLDR: Fuel sticks to cylinder walls and ends up in the engine oil. Since you can't post PDFs on BITOG, here is the...

Did my first analysis on my wife's 2015 Honda Civic. When I changed it, the OLM was at 10% and had been exactly a year since I last changed it. This car is mostly short tripped and I didn't give the oil much time to warm up before I changed it. So unsurprisingly, there is fuel in the oil but...
