So first question is about my spark plugs, currently my engine is at 71k miles and the spark plugs have never been changed. Is this something I need to do before putting the super charger on? I read in the manual that it was recommended to do them at 60k miles but I haven't noticed the car running weird or anything.

My next question is about the type of oil to use now. I heard something about using a different weight of oil when you are super charged, is this true? Last week I had a full synthetic oil change with 020-w something like that I think.

I have another question about transmission fluid. When I went to get my oil change they told me I should do that but I declined. Should I let them exchange it for me?

Also question about rear differential fluid, I am at 71k miles and to my knowledge has never been touched, is this something I need to address right now also?

Pretty much I have only done oil changes to the car I never did anything else. If there is something major I'm missing please let me know, I know going super charger reduces the life of the car but I'd like to do anything I can to increase it :)

If your're going FI then replace the 0W20 engine oil with some 5W30

if you read the owners manual this is also Toyota's recommendation for cars that are used hard

I just got this oil change last week and paid like almost 100$. Do you think it would be okay to run it for the first 5k miles with this oil and then switch to 0w30? or just switch before going FI..

whats the point of the supercharger if you do not plan on driving it hard? better off saving the money and keeping it stock.

Because it's my money and I do what I want. I enjoyed the car stock for just over a year and now I'm ready for more power :)

Just because I have a super charger doesn't mean I should drive the car hard. I just like the feel of the car with it. My boyfriend has dropped 20k into modifications in his car body kits and supercharger suspension etc and shocker, he doesn't do car shows or events and has turned down sponsorships. It's our car and our money and if we just want to be low key and do stuff to make ourselfs happy that's all we need!

I run 0w-20 with a oil cooled turbo so I think your fine to use it.

Quick FYI a 0w-30 oil is technicly thinker when cold and at operating temps the a 5w-30. I wouldn't go any thinker then 5w30 personally

I know my boyfriend wants to get different headers and then he will get retuned, is it the same if I put a different oil in or add an oil cooler down the road? Do both of those require retune?
