Castrol - Power RS R4 4T Engine Oil

When I purchased my Piaggio MP3 500 the shop that I bought it from recommended another brand but then they stopped carrying that and then recommended the new stuff that they were carrying. Well I have always used Castrol oil in my four wheel vehicles so I felt that I should use it in my scooter. One oil change to the Castrol a new filter and a new spark plug and my gas mileage increased from 52 miles a gallon to 58 miles a gallon. It's been hot as Hades here in South Texas this year yet my scooter has run through it with no qualms at all in stop and go traffic as well as 70/75 or more mph speeds to keep up with, or sometimes surpass :) the traffic on the highways. Wow! I love this stuff and obviously my scooter's engine does too!

Castrol-Power RS R4 4T Engine Oil

I purchased the Castrol-Power RS R4 4T Engine Oil for my 2010 BMW S1000RR. This specific oil is called out in the owner's manual as recommended by BMW for the specific motorcycle. It is also the oil used by the BMW racing team is FIM World Superbike. I figure if it good enough for the FIM World Superbike S1000RRs, specifically called out by BMW for the S1000RR, then there must be something special about it. I stocked up knowing oil is headed up again and the price may not be this low again for a long time.

Castrol RS R4 4T 10w-50w

I purchased this specific oil because it was recommended by BMW for my HP2 Sport. This oil is the American version of Castrol Power 1Racing 10w-50w. I obviously don't know if it's any better than other brands but it was the recommended oil and I don't want any warranty issues to pop up over improper oil usage. I will purchase this product every 2500 miles.

Wow, what a difference!

I’ve got an ‘06 ZX10R, at 5k miles I did an oil change using Motul 10w40 conventional oil because I was on a tight budget on the type of oil to choose (conventional vs. synthetic). I rode it for 2000 miles and did a track day and decided to go with the Castrol full-synthetic. I jumped on the freeway and noticed how smooth the engine felt at extremely high rpms...prior to the oil change, the bike was under performing and felt like it struggled @6-8k rpm's...I never really paid any attention to the claims of synthetic oil, but now I’m a firm believer! The difference is like night and day!

Great alternative to Mobil and Amsoil

I have a 05 ZX6R and put this in about 1500 miles ago after running Amsoil from the previous oil change and immediately noticed the shifting was smoother and the vibes were less at higher rpm. I'm convinced this is a great alternative to Mobil and Amsoil but don't tell anyone, you'll the drive the price up! I'm looking forward to the next oil change to see how it looks, definitely will be using this oil again.

Smoother shifting

I bought my 07 Ninja ZX6R used. It had 7300 miles on it. I rode around for a couple days before I got a chance to change the oil. On my first ride with this, I actually thought that I missed a shift. The bike used to shift very hard, but now it is so smooth. Can't wait to see what it is like on the highway!! I will only be using this from now on.

Works Great Under Pressure

Extra boost of power when engine temperature increases in stop and go traffic or hard riding. JASO MA2 rating means "extra grip" and RS means "reduced slippage". Suitable for EBC Kevlar Clutch Kit. 10W50 best all year around protection.
