Engine oil for 7.3 idi?

[chris142]

Todays 15w40s dont sheer much. It may be a 15w35 after 9000 miles. Dont worry about sheer.

Just as others have mentioned, our engines love to drink rotella.
I switched over to delo years ago and that's what we've always used since. I get it at cal ranch for like 13 bucks a gallon, it's pretty high at auto parts stores.

I have run both Rotella 15w-40 and 10w-30 (clearance at Walmart).

My truck uses/leaks 3-4qts every 5k miles. I wil be trying Delo 15w-40 when my current stash of oil runs out.

You shouldn't have any issues running 15w-40, especially in California. Its been below zero up here overnight and single digits to low teens during the day. Even not plugged in my truck hasn't failed to start yet.

I run Delo 400. I only drink a quart every 2-3000 miles. Has anyone tried Rislone Ring Seal in their rigs?

Currently burning a gallon a week (1000 Miles) of whatever is on clearance

I've been running the DELO 15W40 that Walmart sells in 2.5 gallon jugs for about $30. And, like noted above, the old IDI contaminates the oil with soot far faster than it wears it out. So, change often. I could probably stretch that out if I had a good bypass filter.

I change about every 3000 miles or so.

Any recommendations for good bypass filter?

Also, if you can manage it, a centrifugal oil filter works well

You could use a much cheaper centrifuge(PA Biodiesel Supply sells them), but you need a big return port vs a small hose. The air compressor in that centrifuge is to force the oil to drain and make sure there is air space inside the housing of the centrifuge.

Parker Racor makes a pretty nice bypass kit as well.

walmart MOBIL delvac 15-40. 10.47 to 12.97 a gallon. works great in a PSD so it can handle a IDI

for a dollar or two more than the walmart oil its great. ive been using it for years.

Yep thats good oil for sure.

My old motor used to drink rotella as well. I typically ran Delo or vavoline with minimal consumption.

I have used nothing but full synthetic since the mid seventies. When I got my IDI I first used Mobil 1 because I had it. I then went to the Walmart stuff then to Rotella T6 a few years ago. After a couple trips to SEMA asking about oil for flat tappet cams, I now use T6 in everything; no cats. And Walmart has it in 2.5 gal size. Oil is just about the cheapest item in total cost of operation. Don't cheap out.

BTW, I just started with a clean 93 turbo, clean cooler, and a normal filter. It took 13 quarts.

Mine see's very little miles and long sitting. Synthetic would be a waste for me. If I daily drove it I would probably switch to T6
