Engine oil VALVOLINE or Shell

I am using Shell Helix Ultra 5w40, fully synthetic for my Lancer (2006), change it at around 7000 KMs. No complaints, my travel includes short & long distance, very happy & satisfied.

Valvoline MaxLife 10W40. Made specifically for older engines with high mileage.

I just did the restore and protect on my 2015 and let me tell you that it has made a massive improvement. Immediately the engine runs quieter and smoother and after 500km it’s like my engine has much more power.

I think that as a general rule you want a motorcycle specific oil in your primary because of specific additives in it for a wet motorcycle clutch. Just don't use a super slick oil like the Valvoline VR1 Racing blue sapphire stuff.

Why spend more when you can buy Shell Helix Ultra FS 5w40 from Lotus's, Giant or Aeon Big for half the price or less compared bought in petrol stations.

I recommend valvoline syn power mst C3 for Renault diesel engines with dpf filter. Low saps oil which will produce less carbon in your engine. I have 110hp version of 1.5dci and use this oil for last 6 years. Never had a problem and oil consumption is minimal

Valvoline is really good and proves it on tests. Available at any auto parts store... currently running it in a westinghouse 2550dfc

I run mobil1 but my local small engine place that installs and services Generac, Kohler and Briggs swears by Rotella straight 30 weight.

I run Valvoline VR1 20W-50. I believe during cooler seasons you can run a thinner (less viscous) oil.

I've used a number of different oils in my XS400 over the past couple years, can't say I've noticed much of a difference other than when I used a 15W40 the engine was a lot noisier, going back to 20W50 and the engine quieted down a lot.
