I would try this but my car has 82k miles or so. Always had oil consumption and would try anything to lower it

 

Changed them both, after the Pennzoil I had to go to town on a bunch of leaks. Not sure if the oil caused it, or just coincidence, but my TCT rattle went away when I went back to Castrol. This was at around 138,000 miles. I'll probably get laughed at for this but I think seals, and metal gets used to a certain type of oil. Because 0w-40 0w-30 5w-30 and 10w-30 all burned at right around 800 - 1,000 miles/qt, the only synthetic oil that didn't burn at that rate was the oil that the car has ran for most of it's life. Regular 10w-30 edge, which is around 1,500 - 1,600 miles/qt, that and apparently synthetic blend. Well 240 miles now, still right where I left it so I consider this a good sign.

 

280 miles now. I know it still burn some but before every 2 or 3 stops I'd smell oil. So far it's more like once every 5 or 6 stops. And it's only a tiny whiff, instead of having to smell it for like 5 seconds at a time.

I usually drop a hash mark after 300 miles, but so far it's exactly where I left it after the oil change. Which has never happened before since I owned the car.

 

What penzoil was it ultra platinum 10-30?

 

Castrol and Valvoline full syn are pretty much the 2 oils off the shelf I stick to in this engine, which seem to retain their integrity the longest and get consumed the least. Non synthetics typical have the least usage. So if you have a pretty severe usage problem such as the OP, not only is non syn cheaper to top off constantly, but it doesn't disappear as quick. You will want to change it more often however, say 3-3.5k instead of 5-6k if your trying to maintain the engine as long as possible.

 

The current F22 I'm running has about 45k miles on it now and seems to go through just a bit over 1q in 5000 miles.

 

Your completely correct, but it's because of the additives, ex. High mileage oil has additives that make the rubber on seals swell. So if u end up changing to another oil that doesn't have the additive the rubber/seal shrinks more then before creating even more of a leak.

 

Anyone running Eons 10w-30 ?

Is 10w-40 ok for the 2.0's ?

 

Yes, 10/40 is good if your trying to slow high consumption, or if your running the engine hard on the track.

 

5-40 vs 10-30?
