I needed to top up the oil in my 2003, the chevron station

Customer Question

I needed to top up the oil in my 2003 blaze, the chevron station only had 5w20 which I used to top up. Is this detrimental?

Hello I will help you with your question,

The 5W-20 will be fine, you want the slightly heavier 5W-30 or 10W-30 for a full change but adding the %W-20 along with the regular fill will be fine.

Please let me know if you have further questions

Thank you
