Hi guys, as you guys know i just bought my corolla yesterday, anyway gonna have it serviced like this weekend and would be getting the oil and filter changed. i personally switched from a bigger car so i feel the corolla is noisy. From what i heard changing the oil to something that engine oil like the Valvoline XLD Engine Armour SAE: 15W-40 would promote a quieter engine, while a 10w-30 would promote a more fuel efficient engine. 10W-40 would be fuel efficient while giving it a good protection. I bought a 05 with Low mileage 40Ks on the clock... But it doesnt feel like a "new car" the engine is noisy and the car vibrates abit when i put the auto to drive. Question: 1. I got 2 spare engine oil , Valvoline XLD Armour(15W-40) and Mobil Syn 2000(10W-40) Which one should i use? 2. Should i go Repco or Supercheapauto to get my oil filter or go original is there a huge price difference and what you guys paid for? 3. Spark Plugs, Should i go back to toyota to get them or supercheap/repco?? are they cheap? Basically i want it to drive new... I cant believe a car especially a toyota runs 40ks and feels old already... But it seems to be normal cause got a mate with a corolla and it felt the same but to an extend cause his was a manual it felt better cause his car wasnt in drive all the time... =(
