I changed my oil today, I always use the recommended 5W30 (5.5 quarts and filter change). I had also bought 30w for the lawn mower, anyway to make a long story short. After putting the new oil in I relized I had used one quart of the 30W instead of the 5w30. Should this be ok just using one quart of the 30W or do you think I should drain the oil out and start over. Thanks for any help or opinons. Matt

It probably isn't going to destroy the engine but if it were me I would drain it all out.

It's summer time, I wouldn't worry about it. I would worry because I think the car only holds 4.5 quarts with filter. Maybe I'm wrong if its the Duratech. As long as you change your oil before winter don't go through the trouble.

I wouldn't sweat it.

Ever since the adoption of SAE guidelines motor oils don't conflict with one another. You won't harm a thing with what you've done.

Thanks everyone, I will leave the oil in and try to pay better attention to what im doing next time.
