Once I get the car, I'm drivng it home from Louisville, KY to NYC, NY. SO after the first 2,000miles than 3,000 going forward. I only use Valvoline SYNpower Full Synthetic. Been using it in my 2007 Saturn Sky redline with a 2.0 turbo. I drive the car pretty hard time to time. It's a full city car. And I go for 1,000+ mile trips with it two to three times a year. I have over 50,000 miles on the car. It's a great oil. And I will be using it in the Spark.
Changed the oil at 1,000 miles with Mobil 1. Not sure if it was due to the engine breaking in, but it was quieter at idle after the oil change. Next oil change will be at 7,500 or per the OLM. When it gets to under 20% I'll change the oil.
a tiny 1200cc engine developing 84 HP is stressed pretty good ,would use best oil one could ,,id suggest yes ,castrol, valvoline ,mobil one , penzoil, ultra synthetic , probably a few others too as long as get the best and full premium synthetic . being from east , im kinda partial to penzoil , grew up with it in all kinds of hot rods and racing engines , did have excellent results with mobil,one synthetic in my 92 ford 150 pu / with 351 eng, was losing some oil,pressure/erratic; and that cured it completely and sounds and runs much better .and uses no oil,,none!
a few years ago this spark engine would have been a 45 or 50 HP engine ,as now it is what would have been full,race tune then , so it could be kinda stressed if used extremly hard . you want the best for it.( oil and care) with the fuel injection, dohc's and 16 valves , variable valve timming , ect ,,its deffinetly a full race engine n for its size and HP . its a jewell , but not unbreakable ,,cherish it .would have cost you many$$$ to have duplicated it back in the 60's/70's ect
