Hey everyone,
I’ve got a question about oil sampling and analysis. I usually run 0W20 Pennzoil Ultra Platinum during the winter, but in the summer, I switch to 0W40 Mobil 1 FS for autocross. I was thinking of pulling a UOA (used oil analysis) after running the 0W40, but I recently heard something that made me second-guess the timing.
I was watching The Motor Oil Geek on YouTube, and he mentioned that if you switch oil formulations, you should ideally run the new formulation (in this case, 0W40 Mobil 1 FS) twice before pulling a sample. This is because residual oil from the previous formulation (my 0W20 Pennzoil Ultra Platinum) could skew the results on the first run.
Does anyone have experience with this? Is it better to wait until I’ve run the same oil twice before doing a UOA, or would it still be fine to pull a sample after the first run of 0W40? Any insight would be appreciated!
To clarify can I sample the 0W40 after the 0W20. Or should I only sample the 0W40 on my second oil change (after having run the 0W40)? To avoid cross contamination in my UOA. Video starts at 1:00.
Thanks!
