[Martin C]

I’m looking for the recommended oils for B&S, I’ve just dumped my old out the machine, engine & pump oil grade, where ever I read their seem different opinions? Thanks

Yes! We have recently modified our engine oil recommendations to state that you may now use a synthetic 5W30 or 10W30 oil in all temperature ranges. We recommend the use of Briggs & Stratton Fully Synthetic Premium Long-Life Oil.
I use the above but you have got to change the oil filter. I try and change both every year now.

Hydraulic oil? If so then its, Gear oil, EP80W-90 GL-4 is the stuff I use. I buy 5 litres of it.

check with pump manufacturer as wrong oil will kill pump.
Gear oil is generally very thick and designed for Extreme Pressure - hence EP80 90 etc

I believe Interpump use SAE 15W/40 in their pumps but EP80w90 in their gearboxes!

That's what Rutland told me to buy and I have been using it for years now on my B&S PW with an interpump pump.

I have the AR pump

Just ask the folk where you bought the PW from.

A quick search suggests some SAE30 oil for the pump, ideally a non detergent oil as that handles being mixed with a bit of water ok. Gearbox will probably be different

Top man, thanks for the info

It would appear the spec should be on the plate on the pump. Looking at a random AR pump manual there is a table that suggests 10W30 or 10W40 is best but check your exact model on the ar site: Industrial division | Annovi Reverberi
