What is your opinion regarding the Valvoline Synthetic oils? Is it good stuff for our cars? Can it be compared to Mobil 1 oil?

 

I won't leave your post hangin'

Everyone here seems to like M-1.

So far, only M-1 for my CL-S. My van gets Castrol or M-1, where ever synth walmart was on sale.

I guess any synth is OK, as long was you change oil RELIGIOUSLY with a good filter.

 

Read, read then read some more about oil and filters at the below web. Then do what you feel is the best for you.

I'm a engineer that likes to take things apart and compare sooooooo---

Honda filters are not very good. The USA ones anyway. Below is a filter study you might find interesting.

I gave him a Amsoil filter for analysis, so far it's constructed similar to the Mobil1. will post pictures later.

Good oil data located at various sites below

I use Amsoil (Amsoil.com) they invented synthetic oil for auto's and no independent test data yet beats it for 5w30.
