Just because you did not have a problem with your car does not mean a problem does not exist. Not all Ford Explorers with Firestone tires had a problem, but under certain driving conditions it was a big problem. I think that is the case with the Toyota 4 cyl. and v-6 engines. Under certain driving conditions not mentioned in the manual, they are subject to engine gel/sludge problems.

The Camry will smoke when run on synthetic oil. I changed mine back to regular oil and the smoking stopped. Mileage on my car is now 195000 miles. It has never needed an engine overhaul. Best car I have ever owned.

My engine smoked on regular dino oil. That was due to sludge. Got it cleaned (denied warranty coverage for $3000 repair, but later paid back under Toyo sludge policy), switched to synthetic, no smoke every since. Before sludge I changed my oil about every 5000 - 6000 miles, better than the 7500 miles required in manual for my driving. After sludge and engine repair, changing every 4000 miles using synthetic. Overkill? Probably, but I do not want to have to deal with this kind of problem again. Was a nightmare to get fixed and settled.

I have to say, was your previous car anymore reliable than a Toyota Camry? I would be surprised if it was because Toyota's are one of the world leaders in car manufacturing. The problem that you are having is really rare in cars that Toyota manufactures. Sorry to say..

We've had oil related problems on both our Camrys.
Regular oil meant sludging and synthetics meant excessive oil consumption and blue smoke. But we thought it's better to blow some blue smoke and refill once a month than sludge up the engine so it's the synthetics for us. Now new Camrys are built to use synthetics so this is no longer an issue. Sludging is not a problem on 2002 and newer.

I own a 97 with a 3.0 V-6. Never fussed over what type of oil other than 5w-30. No sludging, no engine overhaul, no trouble whatsoever. We have 192,000.
