Hey everyone,
I've got a '97 Tacoma with the 5vzfe. 253k on the original engine and I know it's had a rough life. Peering into the valve cover you can see some minor sludging it looks like.
Are 3.4s more susceptible to sludging with extended OCIs and conventional oil? I would like to run 8k OCI, as I drive all highway 70 miles per day.
Right now I'm running semi syn valvoline 5w30.
Thanks yall
