I have a b&s 5500 generator that I usually run conventional 10w40. Can I run Rotella T6 5w40 or will lower zinc levels affect air cooling? Thanks

Does rotella T6 actually have lower Zinc levels than conventional 10w40?

Which brand ?

Thanks

Rotella kicks Pennzoil 10W40 around the ring and knocks it out in the first round.

Yes the Rotella is fine.

Or get a jug of SuperTech 15W40 and call it a day.

I just bought Carquest SAE40 from Advance Auto for my generator a few days ago.

Remember, it needs an oil change every 50 hours, or every 100 hours if it has an oil filter. So the synthetic is really not needed.

An oil change every 2 days of run time?

Glad you mentioned that.

I don't know anyone here along SW Florida practicing that while they await FPL.

Zinc levels are for valve spring pressures on radical cams. You're likely good, there.

Cooling depends on how hard you run it. The RPMs are the same but the load would be higher. Consider your needs and how gasoline is approx 15x as expensive as grid power. The rotella IS a superior product in general and I want something like it in my backup set, too.

I'd personally run the arguably superior D1 and call it a day.
This engine won't have high enough cam loads that a few PPM of ZDDP would matter, air cooled or not.
A better basestock would likely be of more benefit in any event, and that would be D1.

Thanks for the input. I usually change the oil every 100 hours. T6 it is.

Yes.

The manual call for a 40 weight?

For Florida you do not need any 5W anything. With the warm to hot temperatures in Florida you would be better off with 15W 40, or better yet 15W 50.


Boy will I be happy when ALL vehicles on public roads are autonomous.

Oils with higher spreads between the low and higher number are more prone to shearing, especially in hot applications like air cooled engines running in hot ambient temperatures. A 5W 40 would be more apt to shear than a 15W 40.

+1 I run T6 5W40 in alot of things but only for the cold weather performance. If it rarely got to freezing I'd just use 15W40 in all the same stuff.

Wouldn't this be dependent on the HT/HS ?

If a full synthetic 5w40 were a cP 3.9 and a semi-synthetic 15w40 were also a cP of 3.9 then doesn't that mean equal shear stability?

I thought full synthetics had an advantage of being more shear stable?

Not arguing...just trying to better understand.

The answer is... It depends. In general you want a narrower spread with less VII for higher heat, but depending on how it is blended the 5w40 syn may outperform the conventional 15w40. I don't have a data sheet for the oil so I can't say.

For OPE. Particularly generators, I would go with a quality syn 40 or 50. The better base stocks resist heat better than conventional. The important thing is to make sure you have an oil that will have adequate viscosity at 280-290F. The generators are a special case in that they run wide open under high load for extended periods. The oil gets hot.
