Changed the oil. It was disgusting. Super dark brown almost black and the filter was some Pro-Tec. God The previous owner was just full of crap when he said he gave it a tune up.

I used 10w-40 due to the really high mileage. It was all that they had in stock at the local Oreillys for a 9.99 deal. I just want to start slow and work it up to Synthetic in a few months.

Got my LEDs in for the LP lights and the map lights up front. Installed one for comparison. WOW what a difference!

And, do they still work as bright when all doors are closed and you are just using a maplight all by itself???? Or is it very dim like for most of us?

It WAS dimming. Oddly enough to make it stop, all I did was pull the bulb out slightly instead of pressing it all the way in and it has been working bright both ways. Maybe I just got lucky.
