We have a 2006 Tacoma with 112k miles and a 2007 F J Cruiser with 150K miles. Both have the same 4.0 V6 engine. Sometimes one will sit a few months without use. Recently I started the Tacoma after sitting about 2 months or so and the engine made a lot of racket for several seconds until the oil pressure was up and there hasn't been any problems. In the past 6 years or so the engine has did it a few times after sitting a couple months or so, but not as severe as this last time. Recently the FJ Cruiser did this too. The noise was only the valve train, but the last time on both there was also rod knocking. Both currently have Valvoline full synthetic 5w30 oil, but mostly I've used Mobil synthetic 5w30.
Would a 5w20 be better (the engines have been back spec for the 5w20), if so, what about 0w20 say Castrol Edge with titanium or Mobil one?
In SE Louisiana the temps are rarely freezing and a few months are in the upper 90s.
thanks
