Dupe info I know
I originally managed to squeeze this into the Filters area, as that is what I was changing from the Honda OEM for the ST1100, to the Repco look alike filter.
I also went for Penrite HPR 15 Diesel oil
http://www.penriteoil.com.au/pis_pdfs/HPR%20DIESEL%2015%20AUGUST%202010.pdf, it has been good so far, 2 weeks of stop start freeway riding, and the gear changes are smooth
. The engine appears to be quieter than I am used too, but I will get over it (I had stalled at a set of lights, and didn't know. Maybe it is my hearing that has gone)
.
I had used Belray EXP semi synth oil, sticky gears. Then Honda HP4, sticky gears again, and I am sure my bike was trying to tell me something, as it appeared noisy and some vibration that I had not seen on the Belray. Now gone to Penrite Diesel semi synth oil (Penrite HPR 15 Diesel oil), which I paid about $31 for a 5 litre carton at Repco on special, at the same time as getting their own brand filter too.
Compared to $68 for 4 litres of Belray, or about $80 for 4 litres of Honda HP4, it is a big saving on my wallet too.
Happy so far, and less scared about trying other oils now.
The Penrite oil has a PDF at their website that states that it is suitable for cars, trucks and 4 strokes motorcycles with wet clutches. I could probably put it in my Camry on the next oil change. Cheaper to buy the big drum of it.
About the "change" interval though, I have always changed oil and filter on my car every 6 months, and the bike is getting more use, so I will certainly be doing that every 6 months too. I am not looking to find an oil and filter that can stay in for 2 years myself. I would rather have the regular change, as I also get a chance to look at the oil, check it for sparkly bits
. The oil and filter now are not really an issue, once you come down from the $25 Honda filter, and the $80 oil.
