I bought my 08 second hand, with no previous knowledge of the past owners maintenance records. For a while I regularly had it changed with Synthetic oil (0W-20), last year I started getting oil changes done at the stealership with a friend that worked there. The first time I am not sure if they put 5w-20 or 0w-20 in it, the second time I know they put 0w in it because my friend there told me thats what he put in it. The last oil change I got here in Vegas I had to ask them to put synthetic in it.

Its got me wondering, is it bad to change back and forth for the engine? Next oil change I will do it myself for the first time , so I was wondering if it is worth it for synthetic vs conventional. Gonna be swapping in royal purple.

Edit: Royal Purple is synthetic...Damn I need to research more.

 

doesnt matter

 

Synthetic is a great choice if your doing the changes yourself (less expensive). Remember if you use synthetic you can easily go 4500-5K miles before each change. Changing synthetic every 3K is a waste of money unless MAYBE your turboed.

 

Ive been changing every 5k, I never really paid too much attention to details like this untill recently where I'm caring more about my car now than before .

I thought 0W was synthetic and 5w wasnt. LOL.

 

We live and learn.

 

Use synthetic and use 0w-20. I don't even think Royal Purple offers any oil that isn't synthetic.

 

Use the weight the manufacture recommends which is 5w-20 or 0w-20. A different oil weight maybe be desired (between 5w VS 0w) due to weather conditions i.e you can change to a lower-weight oil for extremely cold weather.

 

Use synthetic, and don't waste your money on Royal Purple. Mobil1 is much better and cheaper.

 

Where I live mobil 1 and royal purple both go for 9 dollars a quart at the local autozone.

 

In NV and So Cal you'll be fine with 10w20...

 

as long as you stick with synthetic you should be good

 

I got my Mobile1 5Qt at Walmart all the time goes for $23 I think best deal. never bought 1qt just too expensive.
