Engine oil Shell or Motorex

He may be using it for the 15w40 weight for noise or lower oil pressure. I ran Rotella in my 94 F150 with the 5.8l gas engine because I bought it with a slight knock. After a while I dropped down to the 10w30 Rotella and ran it for year, lifted mud truck driven daily and in the woods on weekends. It will be fine, just get some clarification on why. I currently run Rotella 10w30 in my 4.2l Envoy.

Tried other brands pero Shell pa rin talaga

I only run 5-40 Full Synthetic on my Armada and all my vehicles in the past. I've never had an issue and only changed the oil once a year or whenever 7500 miles hit. As for what brand, Shell Rotella T6 5-40.

Rotella T6 5w-40 is what I’ve ran in the car ever since it was tuned and I get great feedback from blackstone labs when sending in my oil for analysis.

My experience sa long ride, malamig sya for my scooter. Ayun yung ginagamit ko after mag general pms. Better sya sa ibang nasubukan kong engine oil like petron.

I would order Shell Helix for £20/4L online instead.

I have used Shell Rotella T6 for 19 years on this engine with no issue.

Mannol 5W30 the one with JP at the end

Shell Helix Ultra 5W40 if you like to experiment, will make your bug quieter, but you will discover other noises (like tires, rattles of the trunk cover, gear noise, compressor of aircon).

Honestly Motorex is a good oil, but it is extremely expensive for what you get. I specialize in performing Used Oil Analysis (Worked for Reliability departments for mining outfits) and it’s just a Ho Hum oil.

You can use it for motorcycles I have in the pass only thing I don't like is my bikes don't shift gears super smooth with rotella also in my Yamaha owners manual it says in capital letters do not use diesel oil and I did and I fried my clutch plates and had to put new clutch plates
