These Toyota engines are much like Subarus and show good wear regardless of the oil. I had good success with oil consumption with Amsoil 2000 0w-30. M1 5w-30 should do well and easily make 7.5K miles. Amsoil ASL is another good option. Does the car consume any oil?
Ya, so I'm just gonna stick with the mobil1 5w30. 7500mile intervals should be no problem right?
quote:On my 1991 toyota previa, a "normal" interval is considered to be 7,500 miles, and a "severe" interval is considered to be 3,750 miles. And this would be on conventional oil, but certainly, synthetic oil would be able to do it as long if not longer. I don't think these intervals have changed much in the latter years, so a 7,500 mile OCI would fall under the factory reccomended schedule, and therefore still be within warranty, although the dealer would probably try and find any way possible to say that the car was driven under severe conditions to get out of warranty claims.
Originally posted by 2003TRD: I wouldnt do any extended drain intervals in the 1zzfe engines (at least the ones that were built and put in the MR2 SPyder in 2000-2001) those engines suck arse! Myself and many others (check Spyderchat.com) have had to have long blocks replaced due to some manf defects with the rings (they started using teflon coated rings on the rebuilds. So unless the car in question is seriously out of warranty, I would stick to the scheduled maintanance.
