First time consumption with Napa 5w20 syn

[lipadj46]

I got a little lazy with my mother's 2007 Rav4 and did not check the oil between 3000 and 5000 miles. It never used oil before and I was busy so I let it go. I checked it at 5000 miles because they were going on a trip and I did not have time to change it. I was surprised to find it was down on the dipstick and it took about 3/4 of a quart to get it back to full. Now they come back back from their trip 1000 miles later and I check again and it is low. I drain the oil out and I get about 3.5 quarts (I usually put in 4.5 quarts). I put in Mobil 1 0w20 this time and will let it go 7500 miles, though she just retired so I may have to change it out by time instead of mileage.

I know that 3/4 of a quart in 5000 miles is really nothing but I was surprised none the less because it has never burned an observable amount before. The oils I have used in the past are (mostly) Mobil 1 5w20 regular and EP, Castrol EDGE 5w30 (this was before they had 5w20 edge), and Pennzoil Platinum 5w20. Has anyone else noticed similar consumption when switching between brands of similar oils? I will be keeping an eye on the 0w20 as it is some really thin stuff.

I have never seen consumption when switching brands but others on here have and say it slows down or goes away after a while.

Just keep and eye on it.

A trip?
Heat, high loads and engine speeds will burn more oil.
And who knows exactly how much was in there to begin with?

I did. I knew it was full on the dipstick before they left and that is about equal to 4.3 quarts. They go on trips all the time and this is the first time the oil went down on the dipstick.

how many miles on rav4? i never had any consumption in my high mileage hondas/toyota driving them like I stole it most of time.
Check PCV valve and replace if necessary.

FYI: I have switch between grades, brand, and type and still no consumption, so 5w20 napa syn might not deserve the blame

I used NAPA 5-20 SYN. on my Honda 2.4L Accord when it was last changed. It now has 5700 miles and the OLM is at 30%. The oil level is down about 1/16 in. This is the first use of NAPA synthetic. Have you looked for leaks on your RAV4? FWIW--Oldtommy

No leaks
