    Question about different types of oil and the 10,000 mile checkup

    Hey I am almost at 10,000 miels on my car. I am going to need to get my checkup soon and my 3rd oil change. I jsut had a few questions hoping you guys can answer them for me.

    I want to start using a nice new oil (I've been using dealership stuff). Should I go synthetic or semi-synthetic? What are the differneces? Which one is better?
    I hear synthetic can hurt the engine, and once u go syntehtic you can go back? Which brand should I use? Which is the best? What are teh differences? Let me know, thanks!

    What do they do on the 10,000 mile checkup? Do tehy change anything? Can I get anything performance wise instead of reuglar stock parts if they replace anything? Any input would be great!

    Thanks in advance guys, youre the best!

    I just switched to mobil 1 synthetic at 6000miles. A lot of people use it and I have never heard a negative comment.

    As far as the dealership thing, I am not sure what they do at 10000 miles. I am sure it will say in your owners manual. I would ask the dealer if skipping schedualed maintance will effect the warrenty, if you care.

    Do a search for more info on synthetic oil. You'll find tons.

    All the stuff about harming the engine, can't go back, etc. are just myths and completely untrue. As an example I bought a 4Runner w/ 150,000 miles on it earlier this summer. According to the complete records the guy gave me the truck has had just about every kind of oil available. Penzoil, Castrol, Valvoline, Mobil, even a couple no-name brands. It had synthetic about every 3rd or 4th change throughout it's life. Mobil 1 and Castrol Syntec. At 150,000 miles the motor is perfect, runs like new and according to the shop that checked it for me whn I bought it it has another 150k in it! That's a testimate to the fact that Toyota makes one damn fine motor but also to the fact that all the "drawbacks" you mentioned are false.

    Only reason not to go full-synthetic is cost. I use Mobil 1 myself. It's good stuff and readily available and not way too expensive. You'll see a lot of reccomendations for Amsoil and Redline synthetic oils. They're absolutely awesome but can be hard to find and expensive.

    The 10k "checkup" is just a thing your dealership came up with. The Subaru intervals are 7.5k and 15k. Though I certainly change my oil more often - every 2-3k.

    Skipping the dealer checkups won't effect anything, but skipping the factory intervals certainly can. But you don't have to take it to the dealer for them - you can do it yourself or have another shop do it. I always recommend non-dealer Subaru specialists because I've had horrible dealership experiences in the past (not Subaru actually - BMW and Isuzu - but I just find that you never know with any dealership). Just make sure you document what you or someone else does in case it comes up later.

    Check the periodic maintenance sticky at the top of this forum for the maintenance schedule.
