Well I used the last 5qt jug of my PU 5w30 today. The truck had just under 5K miles on the oil and it starts ticking like it did a while ago. Change the oil and it stops for another 4-5K miles. Used a Napa Gold Too!
... had a 2006 Stratus with the 2.4 I-4 engine, used Havoline dino exclusively ... after about 4K miles the engine would start to sound like an old sewing machine ... give it a fresh oil and filter change and it was good to go another 4K ... that old car had 167K on the odometer when I traded it ... engine still good but the rest of the car was in sorry shape
I notice the Corolla doing some of the same things slightly rougher idle, a little ticking on hard acceleration, but I guess one of the positives about having an oil burner is I'm topping off regularly and can hear/feel the difference of new oil. I can also feel gas differences, I find it strange that the "cheapest" car I have ever owned also is the most finicky. I bet it has to do with age and miles though.
Shearing, fuel dilution, filter being loaded up, or any combination of the three!
Fuel dilution possibly can be cured by a long highway run.
Sudden oil consumption should be topped off with a higher grade or honey for testing.
If no consumption, 4-6 ounces of oil snot/honey can verify if issue is simply visc loss from shearing. Or, refill with one thicker quart with whatever you are using to see if you can go further before noise occurs.
If filter is loaded, change it and top off and see what happens.
It's easy enough for anyone to troubleshoot.
It needs some Super Tech Synthetic!!!!!
My company Jeep Cherokee ticks more as it approaches the end of the OCI.
It's had a steady diet of house brand Warren oil and Hastings filters at 3,000 mile OCI's.
