Ok the great debate still goes on. I have a "90" 454. I started using Mobil 1 at 15k miles it now has 42k. Typically I change it once a year whether it needs it or not. Now I am assuming I have a flat tappet engine and from viewing other debates it seems like using 15-W40 Delo seems to be the oil of choice for this engine. Other than money, am I further ahead to use Delo or should I stick with Mobil 1 10-W30?. I use no oil between changes and it stays fairly golden for the first 2000 miles. Now with this being said, last year I lost the back end of a oil pressure switch and lost 6 out of the 7.5 quarts of oil before I got it shut down. As of right now I have put about 2500 miles on the engine with no issues. ( no oil usage no knocking ) So, Delo or Mobil 1?

Since we have 3 HP and up engines and both gas and diesel we moved to 5W-40 Rotella. I like for our air cooled generators too but mainly wanted higher zinc that the 10W-30 WM full synthetic that I was running in the 1992 454 TBI.

How did you catch you were pumping out all of your engine oil?

When the lifters were clattering and the wife was driving. I've have the story on here from a year ago. That was not the only problem that cropped up that weekend....

I don't really think there is a debate... Or at least a micro debate. It's a picky picky "my oil is better than yours" type of debate.

I've put hundreds of thousands of miles on a camaro with nothing but Pennzoil.
Hundreds of thousands of miles with Mobil 1 full synth
Hundreds of thousands of miles on Oreilly generic.
Hundreds of thousands of miles on Supertec oil from Chinamart.

You know what I found out, they all worked, and my engines never croaked. Imagine that.

I really believe the argument people have with oils is they want to talk micro percentages. Like I said, 81 Camaro with 350k miles (I had since it had 30k) and I used nothing but pennzoil and orange can fram filters that people rag on all the time. I ended up getting rid of it for "other than" engine trouble. (Really it was just rusting through but lots of little things needed fixing and I had a great offer on it).

Anyway, just throwing out my opinion on the oil subject between brands.

My TRUE comment is, JUST BE SURE TO CHANGE your oil and filter every so often (some say 3k some say 5k, I say in between).


4 whopping cylinders on Toyota RV's. Talk about great getting good MPG. Also I have a very light foot on the pedal. I followed some MPG advice on Livingpress.com and I now get 22 MPG! Not bad for a home on wheels.

I'm running Mobil 1 High Mileage formula in my Ford 460. It has a higher zinc content than the regular Mobil 1.

I have yet to find any evidence that synthetic engine oil adds any functional engine life over any dino that meets min OEM specs.

As has been mentioned. Motor oil is basically an emotional issue these days based on a lot of hype from a few sources.

It is like tires. Is a tire rated to carry 3,000 pound load at 35 PSI vs. 2,800 pound load at 35 PSI any better when carrying a 1500 pound load?

Stick with the Mobile 1 but I would start getting a sample of the used oil anaylised. The report may tell you what you are looking for.

you do not have a flat tappet cam & lifters. They are hydraulic. So don't get in a big "zinc" worry.

chevy has not put a "flat tappet" camshaft and lifters in a 454 since 1970 for sure and possibly 1971
