Engine oil Shell or AMSOIL
I have a baleno woth 130k mileage and I have been using shell 10w 40 and the performance and fuel avg is great
I'm a loyal Amsoil user. I usually change my oil every 5k miles. However, 3 oil changes ago, I started sending samples to Blackstone.
First Analysis: paraphrased, engine looks great
Second Analysis 5k miles later: Engine Looks great, Oil still has plenty of life
Third Analysis, another 5k miles later: everything looks great, try waiting 8k between oil changes.
I just put Amsoil High Mileage, 0w20 in my 2012 Camry to see if it will benefit my engine with 221,000 on it. I switched from Mobil 1, which I used for years changing at 5K intervals, but had to keep topping off very often. The engine flush was excellent, the oil I drained only had 1500 miles on it and it came out looking like liquid coal! So a cleaning did take place, I'll see how it goes.
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 also wouldn’t run motorcraft period in my 5.0, in the words of a friend who’s a master mechanic “they sell cars not oil”. Just some food for thought, I did run it until he gave me this one line, I now run amsoil and my 5.0 and 6.2 and 3.0TT are all much quieter, for what ever that’s worth
Me running 5w50 Amsoil SSO full synthetic or 0w50 Eneos or 0w40 Amsoil SSO if being used in winter (down to -40F, and yes, I've driven these cars down to that cold)
Synthetic is better, always. Higher not viscosity has better shear protection. A good additive package that has great shear protection lets the housings wear slower.
Rotella T6 Full Synthetic 5w-40... Burns a little.
