thanks guys
I bought this 07 used with 20k on it.

 

forget that!!! who said you actually NEED oil changes... just wait til there is white smoke, then change it.

 

I've always used a good synthetic (mobil1 or Schaeffers)and changed it every 5000 miles. It usually comes out looking as good as it went in and I've never had any problems. I have considered using Royal Purple in my daily drivers also.I use it in my race car and I dont believe it adds horespower as they claim, but I do think it does as great job of protecting the engine.

 

my husband usually changes my oil and he loves synthetic oil will it hurt anything if you use full synthetic or should you just go with what the book says

 

I ran Mobil1 in a Honda Ionce owedand raced for over 80k miles and never, NEVER had the cylinder head off.
Mobil1 is said to be using a cheaper base these days and so I've given up on it, but have switched to Castrol SynTec.

I believe in synth oils and have had very good luck w/them.
I ran (old) M1 in the Honda for 15kbefore a change,regularly, and it ran as good as the day I converted it over (100+k miles) when I sold her @ 187,000 hard run, rustymiles.

I change oil every 10k miles in my Mazda3, but do a filter change and top-offevery 5k. 'Good time to rotate the tires too while you're (he's) at it.
