Royal Purple, amsoil ea, fram ultra, wix xp and the most popular. Pair synthetic oil with synthetic filter for the win on a long oci.
Agree it is reasonable. Paper works fine at 24 months as well.
OP, is the engine in there one of the sludge monster engines? Does it smoke?
If it has the risk of sludge, which many Toyota v6 engine sof that era did, I'd go slow. Supertech syn may have less solvency than others, but it may also clean.
You might consider doing 1-2 short OCIs on an HDEO as well if sludge is a possibility.
