Going from regular dino oil 10w-30 to M1 10w-30, I stop 'losing' as much oil. Went from like losing a quart a tank and a half to losing like a half quart every two tanks.. The family Accord is turning at 260k miles now, been running strong on M1 the last 100k miles..

 

I run Rotella T5 Diesel Oil 10-30. Mobil 1 is probably one of the worst oils for us old Tappet style rocker people (B series, D series, H series) since the EPA has ordered oil companies to remove most of the zinc content from their products. This is because Zinc is not emissions friendly and now with roller rocker technology is no longer needed. This puts us people out because we start to have rocker pad and cam wear.

 

Where are you getting it from

 

What about Rotella and sensors? Or does it not affect them? I was just thinking about how like leaded gas fucks things up but this is oil with zinc lol

 

Rotella is the shiz

Last oil change I did was Mobil 1 and the most expensive filter walmart had lol. Forgot what brand, but I read good reviews on it.

When it comes to oil I feel that keeping it fresh every 3000 miles is more important then anything else.

 

I run Walmart oil + ZDDplus additive. I haven't decided on a synthetic yet, probably Amsoil though.

ZDDPlus™ - ZDDP Additive for Classic Cars - Agricultural Equipment & More

If you want to have more zinc and phosphorus additives in the oil, then use a "high mileage" oil, they have more additives. The API rating is SL.

The EPA hasn't necessarily required that the additives be reduced. They have required that factory catalytic converters last 8 years/80000 miles. The burned zinc and phosphorus compounds form a coating on the cats, reducing their efficiency. To make the cats last longer, the additives had to go.

H series guys have it really bad with the new oil.

 

I actually spent $200 to prove thise argument I tested mobil 10w30 and royal purple and a new oem oil filter every time I changed.On the dyno my car made 337whp with the mobil and 331whp with the royal purple and this was done with out changing anything but the oil and filter.

i have always ran mobil 1 in all my cars, Some people love it and some people hate it. I just think it thins out too fast tho. And i dont like the idea of that.
