Summer has little to do with it. The Rotella T has higher levels of ZDDP a zinc anti scuff additive that is slowly being reduced and phased out. It's needed on 'flat tappet' cams like we have. 2. spark plugs? and wire set? last tune up I went with autolite and what ever the vatozone guy said gap I think not sure tho (.032) oh also on one of my ignition coils seen to get to hot could it be goin bad or is it bad truck seems to run good tho?? Run NGK plugs for your Z22 motor. The intake side are one range warmer than the exhaust. 3. oil filter and air filter? any better than other?? NO FRAM!!!! NAPA gold or Wix brand are fine. Always change the filter with the oil. 4. planning to top off or replace tranny gear oil Supposed to be done every 30K so probably only done by original owner. GL-4 80w90 NOT GL-5 ever!!! Has to be GL-4 or say 'yellow metal compatible' to protect your copper alloy synchro rings. 5. also plan on fixing leak that axle is having and do new fluid and gasket or what ever requires?? what is the difficulty on this?? Probably the pinion seal if leaking at the front. Check level and keep topped up if not fixing for a while. GL-5 80w90 oil for the diff. 1 Quote Link to comment
