Engine oil Shell or IDEMITSU

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.

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

I have a baleno woth 130k mileage and I have been using shell 10w 40 and the performance and fuel avg is great

I use rotella 15w-40, high zinc content but my engine also has 230k miles

I use one oil - shell rotella. It goes in my XRL my 4.0 Jeep and my 7.3IDI diesel ????

I always used gn4 but switched to rotella t6 15w40 cheaper, full synthetic. it can handle the heat alittle better and I like the shift quality over gn4. Walmart has it for cheap

Shell Rotella (Rimula) 10W40, mines on 165k, 6 months ago I did the O2 Pilot mod and started to use the above oil as it's fully synthetic and made for Buses, Heavy Trucks etc, and so has extremely good cleaning abilities. My oil consumption has dropped almost 4 fold and the cams, rockers, oil filter housing have all been cleaned of the varnish type coating they had too.

I have a Sohn kit and run Idemitsu engine oil in the engine and Idemitsu premix in the Sohn. Runs lovely and smooth and the original cat is still doing the job.

Nothing wrong with LiquiMoly, but I personally find Shell Rotella T6 to be better. It is quite a bit cheaper as well.
