Very sneaky Gaurav, very sneaky indeed, by tagging me, so I get a notification and get dragged into this ! LOL
Gaurav, Rahim bhai how are you guys, loooong time no see! And thank you Rahim bhai for remembering me and your kind words and bothering to look up my old posts
Yes, (unfortunately for some) I am very real and these are my actual experiences, Although having sold the Disco 1 I still Diesel Oil on my catless Range Rover P38 which is now sitting comfortable at 220k kms. There is a lot of research gone into this, specially by hot rod community in the US. Because most old school muscle cars also use flat tappet push rod engines. Just google ZDDP. Now big oil companies are coming out with oil formulas with added ZDDP just for these cars out there. So its not some thing I made up ? Technically the LR V8 is a 60s Buick Engine with LR bought the rights to, and practically remained unchanged till it last production run.
And for people making noise about sticking to "manufacturer" specs, how many of them even bother to read the owners manual, eh ? I can bet 90% don't even know the recommended tyre pressure of their cars ? That brake oil needs to be flushed and replaced every 3 years, coolant every year or two, ( figures may vary ) etc etc.
Or every bothered reading the owners manual ? Do you even know what engine oil is being put into your motor ? Or you just go to the gas station he asks, You want the 3000kms, 5000kms or 10000kms oil in your car ?
Since we are talking LRs here a shot, attached below from the manual for the Range Rover, for countries with temps from 0-40C + use 10-60w oil, and if you read further on it says countries with hot and dusty climates ( which is considered extreme duty by most manufacturers ) an oil change is recommended every 5000kms, when normal oil change ( as in European and North American climate ) interval for the same vehicle is 10,000kms. So how many are using 10-60w ?
L322 Range Rovers, Audis, VWs, BMWs and many more all which use the newer ZF transmissions come with "sealed for life" engine oil, yet the world is filled with people whose transmissions have given up the ghost anywhere from between 100-160k kms. And yet ZF themselves sell replacement transmission oil and filters, and when questioned about their sealed for life boxes, they simply say its the life of the box and not the car, and they estimate the life of one to be around 100k miles after which it needs to be serviced. There is even a huge neo green sticker on the ZF boxes which mention the oil part number.
My other Range Rover has a built in oil service countdown and once reset, it shows next oil change after 25,000kms !!!! Now if I want to destroy my motor I will follow what the "manufacturer recommended". My new RR takes only fully synthetic ( i.e expensive ) oil, but I still change it every 5k rather than the "recommended" 25k by the car itself. Oh and in the manuals and even the oii cap says use only Castrol oils...right !!!
So don't just blindly follow "manufacturers recommendations" use your own 2 cents as well
