OILS AIN'T OILS

Yeah Penrite car oil! designed for LPG machines out performing a well trusted highly regarded motorcycle specific oil.......oh tell me it ain't so!!! <!-- s:roll: --><img src="{SMILIES_PATH}/icon_roll.gif" alt=":roll:" title="Rolling LoL" /><!-- s:roll: -->

 

Actually it is so. LPG is a very harsh fuel, typically working the oil very hard. So Penrite already being a decent oil, being LPG specific means it is even more high temp stable and likely to last the full service period.

The only thing that makes motorcycle oil specific is the picture on the bottle, and the pricetag.

 

After reading a thread on Netrider, My brother became became very interested in Castrol Delo 400 15W 40. It's an oil mean for Diesel engines, but is of a very high grade and also very cheap. He's bought a 20 Ltr drum for I think $90

I am almost about to give it a go for the next change but I thought i'd see what fzr250.com thought about it.

The guy at the local oil shop said that he'd only ever sold it to harley riders, and some american guys with fully worked harleys ONLY use this stuff. If it is as good as they say, then its a very good deal. I usually run 10W 40 Castrol GPS semi synthetic and I live in melbourne. This oil only comes in 15W 40. Is that ideal?

PS just noticed it is a mixed fleet oil- so can be used in petrol and diesel engines.

 

So since it doesent get below around 4 or 5 degrees celsius, 15W40 sounds ideal.
When Ive done enough kilometres on my new engine's 10W40, Ill try the diesel oil and see if there are any adverse effects of a 15w40, being a little thicker. It'll probably be fine.

 

its only thicker at startup. operating temp viscosity is similar, so that will have no effect. if you find a difference, it will be in oil quality as opposed to viscosity and fluid friction.

If your playing with oils, although more expensive (around $11 per litre) i maintain that PM is well worth a go. Still, after all this time getting people coming to me with surprising rsults.

While we're at it, diesel oils "typically" (only loosely applied here) havrnt dropped shear resistance, as additives that affect shear resistance havent had to be reduced for later API rating like petrol oil has had to.
