CarreraG50 Posted 15June, 2018 Report Share Posted 15June, 2018 I know most of this stuff is regarded as snake oil, however with modern science maybe some would work, Interested to hear peoples thoughts, the below specifically mentions flat tappet camshafts (air cooled PORSCHE engines) http://www.supercheapauto.com.au/Product/Rislone-Nano-Prime-Engine-Oil-Performance-Booster-500mL/556529 Link to comment Share on other sites More sharing options...
tazzieman Posted 15June, 2018 Report Share Posted 15June, 2018 Says nano so it must be good ;<) If you rarely drive your car and the oil drains off (parts almost dry out) that does expose the metal at startup. And if you scream off without warming up , that's not the best. How the nano miracle translates into a performance boost is not for me to speculate. And the other claims sound very snakeoily to me. Gut feeling is to avoid additives & use a recognised recommended oil. But it's like vitamin supps , if you believe in magic - it works! Link to comment Share on other sites More sharing options...

Vitamin Supps, got a friend who works in the complimentary medicine field, reckons its the hypochondriacs that keeps him employed. Link to comment Share on other sites More sharing options...

That industry has been slammed by science. Anxiety +/- "fear of missing out" underscores a large % of the wheel of economy. Link to comment Share on other sites More sharing options...
Kammo Posted 15June, 2018 Report Share Posted 15June, 2018 Don't know about the other additives but molybdenum disulfide is blended into some performance oils (Motul, Liquimoly). The science is there to support its use as a lubricant in the combustion cycle and there's at least some anecdotal evidence suggesting it does work to reduce wear and extend engine life under some applications but the economics of it are another question. If you're worried about your camshafts it's my understanding that you need an oil with a high ZDDP content. It's probably better and more cost effective to just source the appropriate oil. If your car is mostly daily driven I would suggest taking the $50 you would otherwise spend on this stuff and put it towards a decreased oil change interval and you will get a better result.

Thanks Kammo, at most my car does a couple of thousand kays a year, and until recently was run exclusively on Brad Penn 20w50 high zinc oil, just recently I have changed to PENRITE 10/10ths 20w60 zinc 2200ppm but it hasn't been in their long enough to do a comparison (ATM oil pressure is slightly up in relation to the BP) Cold start is my real concern after the car has been sitting for a few weeks(or months sometimes) Link to comment Share on other sites More sharing options...

Pull coil lead and crank it with the starter until oil P rises. Then reconnect lead and start up. Think of it as foreplay. Link to comment Share on other sites More sharing options...
Peter M Posted 15June, 2018 Report Share Posted 15June, 2018 You are trying to solve a problem that doesn't exist. Save your money and find something important to worry about. And Mezger's don't have flat tappets, sliding finger actually. Link to comment Share on other sites More sharing options...

This could be so easily fixed by giving me a spare key while you're away & I will ensure it gets driven mildly until it is appropriately warmed up & then wildly to distribute oil as & where needed. I won't even charge you a fee for this service AND I live in Brisbane. Now, I am glad we've finally got that settled.......I will await a PM with the location of the spare key to your house & where the car keys are kept. Oh & please ensure the fridge is stocked while you're away I can't stand stinginess when I am doing YOU a BIG favour. You're welcome....................................................waiting.............................................. Link to comment Share on other sites More sharing options...

Good advice. Just do an oil change every 6 mths, you will have peace of mind with fresh oil and filter and it's really not that expensive compared to a rebuild.

Peter M Posted 16June, 2018 Report Share Posted 16June, 2018 I think shorter change intervals is another panacea to a problem we don't have. For our cars and how they are driven, shorten beyond the common habit of 1 year or 10,000km (whatever comes first) won't provide any measurable benefit. If fact I can only see dis-benefits such increasing the risk of introducing external dirt into the engine (important in pre 964 911's), additional cost and wasting perfectly serviceable oil. I'm confident that any reputable oil analysis company would laugh at even the 1/10,000 recommendation and would suggest 2 times or more would be perfectly safe. Sure there are caveats, if you only do short runs, operate in dusty environments, run K&N style filters, have a set of carbs with dirty big accelerator pumps or race but I think the reality is that modern oils, as they are, are very good and really our cars lead charmed lives. But each to their own!? Link to comment Share on other sites More sharing options...
StevepGT3 Posted 16June, 2018 Report Share Posted 16June, 2018 When you have the correct amount of protection, it is impossible to add more protection. Oil and additives are a car nuts version of anti wrinkle cream, there is actually no way to measure the benefits because of a million variables.

tazzieman Posted 17June, 2018 Report Share Posted 17June, 2018 I have read that "too frequent" oil changes are harmful. But I cannot find the reference and not sure if it applies to modern vs old engines. Just something else to keep you awake at night...or not. As usual, it all depends...

Maybe if you are heavy handed tightening the sump plug or cross threading the plug or the filter or filling the oil in the wrong hole. Always use the 710 plug hole.

tazzieman Posted 17June, 2018 Report Share Posted 17June, 2018 https://www.scientificamerican.com/article/oil-change-truths/ The fact is some people like to shower 4x a day and keep their homes clean with chemicals that kill all but 0.1% of the deadly germs out to get them. Then there are the rest who just get on with life! Is it even possible to wear out the engine in a garage queen car? Link to comment Share on other sites More sharing options...

People will post the results of a virgin oil sample and then one from a recent oil with the same oil and use the "jump" in wear metals readings to suggest new oil "wears" the engine more. They forget the engine carries about a 1/2 litre or more of old oil from one change to another and this is the cause of sudden change in results.

In the case of an old series Landrover , it's about 5L (of virgin oil). That's why my original Rover engine is unworn! Ooh I do love a good oil thread.

jakroo Posted 17June, 2018 Report Share Posted 17June, 2018 1 hour ago, tazzieman said: .... Ooh I do love a good oil thread. as do I. The proper solution is to drive the vehicle more often. Step 1: Let the engine get warm, drive it harder, engine oil gets warmer, drive it harder again, engine oil gets warmer still and so on. Step 2: Repeat weekly. Suddenly the kms are up and the service interval is achieved. Step 3: Change oil, filter, apply grease to bits n pieces. Return to step 1 and repeat.
