Good Day tuners

I currently have a 2006 Fielder

I was currently Running Castrol Synthetic in my engine with absolutely no issues at all. ....

BUT when i did a tune up my mechanic put in Castrol GTX ..... I immediately felt like the car was toating alot of weight or something ......

What i will like to know is if to return to the Castrol Synthetic Oil ..... ?????

ORRRRRRRRR ..... can I get some info on some other options that may be used .... and the benefit associated with using such brand !

E.g. Quaker State, Royal Purple, Etc ......

Apparently, the best rated oil on the market is Amsoil Signature Series. I use the 10W-30 with no problems. It's about $300.00 per gallon and is supposed to last for 15,000 miles (about 24,000 km) for severe service interval change. I would say change it at 10,000 miles (about 16,000 km) though. I use a Royal Purple Extended Life filter with this as well.

I don't like the idea of running a synthetic, then normal dino oil, then back to synthetic just like that.

If I were you, I'd do a flush before switching back...and change that mechanic.
