Curious about this....what makes it a great recommendation for my ol' American farm truck? I will say that I ran QSFS 5W-30 in my Frontier to replace my beloved Magnatec and that engine loved it. I have respect for the QS stuff now.
350 TBI Oil Recommendations?
- Thread starter Frontier4000
- Start date
Any synthetic 5W30 is what I would use.
@Frontier4000, it looks good on paper with approvals and VOA looks strong. $22.97 retail for 5 quart jug at Wally World is reasonably priced to me.
For $25 i'd buy it just for that nice black and red jug. Yeah why not. It could have a bit extra moly but that alone will still make it underperform a cheaper but better euro oil with specs like Porsche a40, BMW ll-01 and mb 229.5. That oil would never pass those requirements.
Thanks. I'm giving this stuff a really hard look along with 10W-30 T5 Rotella.
I used euro 0w40 mobil 1 in my 83 305 for yesrs. It was my cold weather winter bester. Euro oils typically have more zddp and are just tested to stricter requirements than typical 5w30. My car got sold several years ago and 2 owners later it was recently spotted pulling a trailer.
A TBI 350 has a flat tappet cam but it's really a very mild cam with not much lift or high valve spring pressures, just about any full saps 30 or 40 grade will work fine, although ofcourse running something like VR1 10W-30 with high Zddp won't hurt it at all.
The euro oils such as the m1 0w40 is considered "full saps". I'm not the guy to explain what it means though.
I run this oil in my flat tappet 1976 Oldsmobile 350 v8, my 2005 Silverado 4.8 V8 work truck and my lawn tractor and push mower along with generator.
Sulfates ash phosphorus sulfur
It doesn't need any special oil. Low compression strength valve springs are just fine with any current SP oil.
Clean and full. It's impossible to buy a modern API certified oil of 30w or 40w that won't surpass the oil it was designed for.
I have seen those engines go over 400k on whatever oil was around.. nothing special. I also have never seen one eat a cam so I wouldn't worry too much about the flat tappit thing.
Still millions of those,jeep 4.0's etc still running around with flat tappets with no troubles.

after the nuclear apocalypse, mutant cockroaches will be driving around in TBI smallblocks and Jeep 4.0's ... using Supertech.

My '94 has a TBI 305 and I've been using the Napa brand 5W-30 High Milage in the red jug. No issues at all. I change it every 3000 miles which is right around a year.
How many miles does it have? I put in the 5W-40 Euro this weekend and now she puffs oil on startup. I'm sure it's valve seals, but it didn't puff or burn any when I bought it. Of course, I have no idea what oil was in it. It did have a GM filter though. Wondering if the 5W is a little thin on startup for old valve seals. Does the Napa HM have seal conditioners that may help?
Put that stuff in this weekend and now she's puffing on startup. Didn't do that with whatever was in it before
And when those die they’ll get thrown into a crusher where the hydraulic pump is being ran by a 300 I6 that’s received nothing but top off oil for 30 years
Put a bottle of Liquid Moly Motor Oil Saver in it or Schaeffer Moly EP for any burning oil.
