Oil ???

the dealer told me the scheduled interval on oil changes for my 2014 Cruze is every 7500 miles, and that get's a synthetic blend. I'm trying to decide if its worth swapping from the synthetic blend to a full synthetic and change the filter every 7500 miles and oil every 15,000
 


I highly suggest not going over 5k on a 1.4T.

Smell the oil when it comes out and feel it, the turbo gets that oil so damn hot. It's burnt and nasty after 5k even with the best Dexos valvoline oil we sell at my work.
 
Only time I've ever used full synthetic was because the kid at the counter insisted VR-1 was ALL synthetic. So I got one oil change for the flat tappet car in synthetic at conventional price. I liked it. In my daily GTP, I use a blended oil and go 3,500-4000.

I'll have to remember that, the dealer kept insisting to my grandpa to let the DIC show like 5% oil life before bringing it in.

Valvoline is crap! crap I tell you! BTW if you didn't know valvoline is made by Ashland Inc which is the same as NAPA oil.

I've been waiting for someone with more experience to chime in. I would imagine the turbo gets the oil hot because the intercooler is supposedly inefficient. would you recommend a switch to full synthetic?

I used this Royal Purple & was strongly advised not to, so I then went to Mobile 1.

Oil is oil, synthetic is synthetic.

Valvoline to Mobil 1 to Castrol, the motor will not know any different and they all must meet the same exact standards to be ran in a newer cars that call for dexos or whatever else. Cold weather testing is not something I will get into as certain oils do flow better at those temps but thats not what is important.

Your Cruze 1.4T can run the semi synthetic oil because it likely has or meets the dexos requirement that GM wants. Because it's turbo'd and the fact that they get so damn hot, I would change to a full syn just for that reason. A longer lasting oil is what I would want to run.
