Customer Reviews for Silkolene - Pro 4 10W-30

November 30, 2020 - by Juan-Martin

It's Oil.

I've only done about 100mi since changing the oil, but it seems to be doing the trick (in an '08 CBR1000RR) - nothing has given up the ghost yet. Gear shifts seem possibly a bit smoother compared to the last stuff, but it could of course all be in my head... Again, SBS service is fantastic.

Me and the old girl love this oil

Again I can't fault SBS service, it's 2nd to none! As for this oil my Blade loves it with a noticeable difference in the gear shift and performance! Among the top contenders I've found this to be the best by far! I highly recommend it.

Premium oil, you get what you pay for

I have tried most 10W-30 oils in the bike and this one has produced the best results. My CB650F is now turbine smooth throughout the Rev range, engine breaking is softer and gear change is much slicker especially first to second. No more missed shifts or clunking as each gear is selected. Very impressed and this is now my go to oil.

Makes a big difference

It's really worth making sure you use oil that meets the right specs for your particular bike engine. The Silkolene range of oils are great quality. They really make a difference in performance and economy. Well worth it.

Excellent product

Very good product, I had been using cheap semi synthetic oil until I decided to try this one. Now my bike has less vibrations coming from the engine. Gearbox is also changing much better. This oil is light yellow in colour so it's easier to see it darken on the dipstick as it gets dirtier. Have a happy, fun and safe ride!
