With higher than stock oil pressure/high boost levels you need high flow rate. In a race application flow for lubrication/cooling and stopping big debris is more important than fine filtration since the engine gets rebuilt every 2-3 races (depending on the engine and type of racing). My xterra...
It’s not uncommon to get down to 10-15 F for a few days in the winter, especially in the mountains. Average winter temps would be in the 20s and 30s. Kicker is that I’m usually out on the coldest days since that’s when the ducks are flying!
I would argue Wix and Fleetguard to be equal or better quality than most fram filters. Fram has improved a lot of things especially with fram ultra but I still don’t use them on my vehicles. My father built GM and Mopar race engines and always told me no matter what not to use the orange can. He...
I’ve read your xterra thread, good stuff man. Glad to see the syn blend and conventional on a shorter OCI was working for you. Can I ask what your usage is/was for that vehicle?
I like how smooth it is with synthetic blend but I don’t want to have any issues when summer comes and it gets real...
Wouldn’t 0W-40 be a better choice for year round since it theoretically flows better cold, and also has higher viscosity when hot?
I know oils have come a long way even in the last 30 years but I am still skeptical of oils that have such a wide viscosity spread, would they not have to use a ton...
Good to know about carquest premium, I always thought of carquest as a cheap jobber filter. Glad to know that’s not necessarily the case. I’m a big fan of Wix for most applications, I used them while servicing 4-stroke outboards when an OE filter (usually Denso) wasn’t available. Have half a...
Longtime BITOG reader, first time poster.
Currently have 192k and some change on a 2012 xterra with a vq40de 4.0 V6. Owners manual calls for 5w30 in most climates with a change interval of 3750mi. I change my oil and filter every 3k. Along with commuting ~30mi round trip I use this vehicle for...
