Hello all, on my 2014 Honda j35 v6 engine i recently put in 5w30 VRP. I would have preferred to run 0W30 but thats not an option with VRP.
Originally I always assumed 0W was better for cold starts no matter the temp but after receiving good knowledge and advice from this forum, it seems to state that SAE J300 is what matters which details the crankability and pumpability
Furthermore a 5W and 0W would technically have very similar crankability and pumpability at temps such as 10F and etc. Apparently this association remains the same up until super cold temps such as -20F where someone would probably want to switch to a 0W as it won't hurt
I wanted to ask however, lately the temp has dropped to 10F on my morning cold starts and lately ive been getting a cold start brief slap/squeal noise due to the cold temp. I have troubles explaining exactly what it is but i believe it could fall under the category of cold start noise. It just happens when I first crank and the engine fires up, after 1 second the engine sounds normal. It's not a grind or anything, just sounds like a belt noise and or a slap type of noise. I understand this isn't helpful but I won't be able to post a video for a bit and I truly think I have heard similar noises on other cars in the cold. Posting a video would probably just blame it on my vehicle but i am certain i have heard these noises on other vehicles
What I wanted to ask, is this a oil related noise presumed? or is it a noise due to belt contraction or metal type of contraction due to the the cold. I feel like I have heard it less on vehicles when they are running 0W but that shouldnt really matter at this temp unless I am wrong. I can't use my car as an example but i have a memory that when I was running 0W last month it never really made these noises.
anyone have a similar finding? ty
