Engine oil Shell or Lucas

Fixed many ls engines with excessive oil burning by switching them to t4 rotella 15w-40. The rotella t4 flavor of it is a fantastic oil. If you're engine has good oil pressure and isnt burning oil then theres probably no need to for it but its not gonna hurt a thing. Gen 3 ls engines arent some super tight tolerance engine, i probably wouldn't put 15-40 in a motor that calls for 0-20 but your 5.3 will not care at all.

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.

Rotella T6 5w40 in my EJ255, its helped a tad with the leaking until I can get everything apart to seal it all up again.

I used the middle one on an old 200,000KM Porsche Cayman S that was burning oil. It made it worse, smoke started coming out of the engine when the oil cap was off and I felt like the engine would soon die.
