I've always done the oil changes on our family vehicles and equipment since age 12. Growing up we ran Mobil Delvac in a lot of vehicles, and then in my leaky ones like the 4-cylinder Pontiac I ran Castrol GTX to supposedly help prevent burning. Later on I used Quaker State conventional.
Over the years I switched to Mobil 1 full synthetic on all our vehicles, with some testing of Penzoil Platinum on the newest one just to see how it upheld.
My question is for the older Dodge Grand Caravan we have, it seems to burn oil by at least upwards of a quart between oil changes, but does not leak or smoke. Odd. I do change the oil in all vehicles around 3,500 miles or once a year if they sit in the drive way a lot. I've used Engine Restore in the Dodge and even Lucas Oil additive, but nothing too amazing results. I am curious if going from Mobil 1 Full-Synthetic to something like Valvoline Synthetic-Blend for high mileage engines would hamper the vehicle's lifespan or performance versus just sticking to the full synthetic. Not too, that I run the FRAm Extra-Guard synthetic oils oil filter on the vehicles, too.
