I recently bought a 2013 Toyota Sienna with 95,000 miles on it. The manufacturer recommended maintenance plan calls for 0W20 with 10,000 mile OCI. I've been doing some searching and it looks like the 2GRFE engine is pretty happy with a number of different brands and weights. I'm thinking I'll probably stick with the manufacturer recommended 10,000 mile OCI with a 0W20. The trends I observed here seemed to indicate that Mobile1, Castrol Magnatec are among the favorites for this van. I'm thinking of going for the Magnatec due to reports of quieter engine operation, and hey they price is pretty good, at least in my location. Though I did see one really good 10,000 mile oil analysis using the Walmart Supertech Synthetic so given the price there that's pretty alluring too. I feel like the bigger question for me is what filter to go with. I've generally used Wix on my other vehicles but I'm wondering if I should move up a step for the longer OCI. Maybe the WIX XP, or Fram Ultra. Also, it seems like it would be hard to go wrong with the oem filter. Any thoughts? Another interesting twist is that the dealership gave me a "free" drivetrain warrantee, unlimited miles and unlimited years, sounds a little too good to be true to me but that's what they said. The "free" warantee came with two free (synthetic blend) oil changes at 5,000 miles/5 months. So if I go with the full synthetic 10,000 mile / 1 year OCI it's really only like getting one free oil change. With the dealership being an hour away I'm trying to decide if it's even worth it. The sales guys was like "oh you definitely want to get your oil changed here to make sure you get your warantee" the paperwork guy was more like "it's probably a good idea to get it done here or at an ASE certified shop but just save your receipts if you do it yourself." I'm thinking the warantee is just their way to get people to bring the vehicle to them for service. Well that's a lot of rambling but I'd be interested in everyone's opinions on any part of that.
