10W-40 instead of 5W-30?

[Black Bear]

I have a 1995 Toyota Camry (5W-30) is the manufacturer recommendation for it but I have 6 quarts of (10W-40) in my garage I would like to get rid of. Can I safely run this oil in my Camry during the warm weather months? Thanks

I would not. If it was a 1978 Pontiac Bonneville than no problem!

My reasoning is these engines are built was some seriously impressive tolerance standards. The extra weight could starve the bearings and lead to disaster. Its not likely but it could happen. There is also a possibility of lowering your fuel economy. The harder it has to work to lubricate itself the more fuel it will use! Proper Oil weights and filters are increasing more important with the development of "variable" techknowlogies.

If it is high milage and has lots of wear already on it, you can probably get away with it ok, but you are still taking a chance. The engine was definitely designed with tighter tolerances for 5W-30 or 10W-30.

I would give the oil to a buddy with an older truck, and spend the $10 and buy the correct oil for your car!

Yep, I would go with the correct oil weight. To small of an item to buy, verses the possible risk.

That is a huge jump. During the summer, you might get by with it. Come fall and winter you will have issues, if not a failure between now and then.

Good luck

I'm glad I asked first. I will give it to a buddy or donate it to the County Re-Use room. Thank you all for the responses.
