There are plenty of posts here from our friends down in Florida regarding the use of 15w-40 in generators. I think that Cujet has a lot to say on this.Thanks.
Do you have any evidence that you have a shearing issue now to be concerned about?
Gensets aren't typically quad cam high specific output DOCH utilizing feet of timing chains that shear oil heavily.
Often times narrowing the spread ends up degrading the base oil, with the highest base oil level being the "0W" variant.
Are you sure that isn't the case in your choice?
Id be interested to see if you ran some UOA's
I ran some on my Onan 8000 running off the shelf 0W-40 and it was fantastic showing I could go for far longer than the recommended 150 hours, holding up just fin e in an oil known for shearing.
Neither my 20KW Kohler, or any other gensets recommend increasing the W rating in hot temps.
Where did you get it ?Rotella T5 10W-30 in my Predator 4000. Just added a magnetic drain plug to help catch particles.
It was one these. https://www.amazon.com/gp/product/B07B259KJ2/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1Where did you get it ?
15w - 40 oils are better oils than 5W-40 oils.huh? ....help me out
15w - 40 oils are better oils than 5W-40 oils.
I bought a couple of these for my Wen generator and Generac power washer. They seem to work good and always have a small amount of debris on them.
i use them in my generator, pressure washer, and log splitter.I bought a couple of these for my Wen generator and Generac power washer. They seem to work good and always have a small amount of debris on them.
just my $0.02
Does Walmart sell 20W-40?Is that universally true?
Better in what way, sometimes the base stock gets better, sometimes it seems to get worse. Add pack?
I get that it probably has a higher HTHS number - but how much higher?
IF you are going to address a hot running condition by upping the W number - why not narrow the spread further by going to 20w-40?
They sell 25w40 marine grade oil. The only 20W40's I recall seeing anywhere were specialty types for motorcycles and such.Does Walmart sell 20W-40?
