Half a Quart Short

[Alamogunr]

I've been using Schaeffer,s 9000 in my 2006 Avalon. I got ready to change it today (Approx. 9500 mi.) and couldn't find the
extra ½ quart of oil. I know last summer I had 6½ quarts left. What is the opinion of the experts? Can I top off the oil with a ½ quart of some other synthetic? By the way the specs say 6.4 quarts w/filter.
Thanks

Any brand oil will be just fine. If it were my car I would just add a whole quart of oil.

Put in you 6 quarts then check it. Might not need the .4 quart.

I would not add a whole quart if it is going to set you above the max/full line on the dipstick.

Add just enough synthetic(any name brand) to get you in the Mid high point on the dip stick.

Call it a day.

No worries!!!!

Thanks, I'll pick up a quart of Pennzoil or M1 the next time I'm in WalMart. I think I like the Schaeffer's but I have to order it a case or two at a time. I'll wait until the UOA comes back on this OCI before deciding about reordering. This OCI was right at 9400 mi.
Thanks again
John

Schaeffer's 9000 series is a great product, but if you want to save some money, their 7000 series is also a great product.

Will the 7000 go 10k miles if a lot of highway, say in a 2009 Camry?

Sorry.. gotta hijack... What detrimental effects, if any, would too much oil cause?

[Mr Nice]

Are you sure about a clogged cat ?

If enough oil is added above the full mark to cause the bottom of the crankshaft to be in the oil, then it will be beaten to a foamy froth and the air entrained oil will not lubricate properly, could cause engine damage. That said, most vehicles have a fair amount of leeway. Need to check manual. No I would not put a whole quart for 0.4 qt, but I do often run mine a quarter inch above the full mark, but my manuals show me where it can safely go and that is much higher up the stick, say about half an inch above the full mark.

As Johnny said, you may not need the extra 0.4 qt. Check it on the stick before adding.
