oil

i have a 2006 kia .is it alright to use 20/w/50 castrol oil in it. thanks

Only if you live in a hot desert. Best is 5W-20 unless you live in a very, very cold place then 0W-20. I live way down in SC where it seldom frrezes and I'm using full synthetuic Valvoline 5W-30 because that's what was on sale.

5W-20 is becoming the norm for most Kias but temperatures need to be considered along with what your owners manual suggests.

Yup. Long as you stay away from a 10W-30 and keep the first number small you're good to go. One of the best synth blend is FordMotoCraft 5W-20 like they use in Cop cars and the way they abuse and engine it'll hold up under them then it should do fine for me putting around town.

"Interested in using Amsoil at a discount?" I can help. I ike Mobli 1 but my drive style not severe enough to warrant usng it.
