[quote=”jay_ie” post=49614]With regards to oil grades look for the German manufacturers approvals, Mercedes,VW, BMW & Porshe on the back of the oil container.
As a rule of thumb these guys are really strict about oil quality so if it has their endorsement you can’t go wrong.
(you’ll be surprised how many top end oil Brands don’t)[/quote]Meeting the performance standards for motor oils intended for European cars is not an endorsement. It just means the oil meets the performance standard required by a given European car company, i.e. BMW LL-01. This is not a BMW endorsement, just an oil performance standard. In the U.S., we use API ratings, such as SL, SM and the most current is SN, but European car manufacturers have their own standards because the vehicles in Europe generally have to deal with very different usage compared to American cars, so the motor oils must meet very different performance standards as well. This is why the American Petroleum Institute, (or API), oil standards don’t apply to European vehicles and vice versa.
[quote=”randomman” post=48926][quote=”jeffrey” post=48737]So Mobile 1 isn’t a pure synthetic? (hhmmm..I hate it when a company bs’s me.) Is there a way to tell on the bottle? Group III’s or some such? …and what is the real deal?[/quote]
mobile 1 is NOT 100% man-made. it is a PAO blend (group 4). mobile 1 is still good. unless you track your car regularly there is no point in getting a pure group 4/5 oil[/quote]
As their website states, Mobil 1 is indeed a 100% synthetic motor oil using a Group IV PAO basestock, which is man-made.
Top performing synthetic oils typically deliver better fuel economy, more power/throttle response, superior high and low temperature engine protection, easier cold winter engine starts, superior lubrication/reduced engine wear, reduced emissions, an internally cleaner engine, reduced engine operating temperatures, etc. These are all benefits any motorist can take advantage of.

[quote=”Lord Ihcalam” post=48665]i think because of a court case, anything labeled full synthetic is fully sytnthetic oil. major brands such as catrol and valvoline and quaker state sell semi synthetic or synthetic blended oil. penzoil does too, but i was taught by my grandfather (a master mechanic for over 50 years) to never use penzoil, not even in a lawnmower. you can usually tell the difference by bottle color, silver is often the blend gold the full, or the prices, semi will be somewhere halfway between standard motor oil and full synthetics.[/quote]
Most, “synthetic oils”, that you see down at auto parts stores, (and I suspect some of the O.E. vehicle branded, “synthetic oils” as well), are what is known as Group III, “synthetic oils”. These oils are merely petroleum oils subjected to more refining and they are not true Group IV PAO or Group V Ester based synthetic oils that can have a vastly greater film strength than petroleum, (Group II), and Group III, “synthetic oils”. These Group III, “synthetic oils”, also don’t share all the superior performance and protection characteristics that a true Group IV or Group V synthetic oil offers, such as superior high and low temperature performance/protection, superior heat transfer characteristics/reduced engine operating temperatures and traditional PAO/Ester based synthetic oils are totally devoid of all the naturally occurring contaminants that can’t all be refined out of a petroleum oil and this is one of the keys to understanding why PAO/Ester based synthetic oils are so superior.

[quote=”Shizerproject” post=49616]Most german manufacturers only specify semi synth too as thats all most applications call for[/quote]
At very least, BMW, Porsche and Mercedes Benz all use 100% synthetic motor oils with recommended drain intervals of 1 year/15,000 miles.

[quote=”musiclover2000″ post=13454]I’m using Mobil one high mileage. The oil was changed in July and since then the oil has only 3000 miles on it. I’ve heard synthetics can go longer then convention oil. The car is driven to work and home mostly on the interstate.
Thanks for your help[/quote]
Mobil 1 Extended Performance has a recommended change interval up to 15,000 miles.
Contact Exxon/Mobil at their website for the best advice on using their products.

[quote=”kaynick1218″ post=29166]I just got 4 new tires for my 2007 hyundai sonata. The manual says it takes v or w rated tires but i got t rated. Is this a big deal?[/quote]
Yes it is a very big deal to do against the advice of the engineers that designed your car. A V rated tire is a high performance tire that provides premium handling, braking and accident avoidance capability. A T rated tire is not. The wrong tires are on your vehicle.

[quote=”MD1032″ post=23068]I should have specified that he knows I do my own maintenance (except oil changes…I hate doing that myself). He was just trying to help.[/quote]
The only thing he was trying to, “help”, is the amount of your money in his wallet!
I’ve spent 25+ years in the automotive repair/maintenance industry and gaskets of any type are not a scheduled maintenance item! There’s no need to ever replace a gasket unless it leaks.
You have unfortunately come across a dishonest person and are being lied to. Run away and never go back!
To help other consumers to not be ripped off, you should report this crook to your state’s Office of Consumer Affairs and the Better Business Bureau!

Old saying; if it ain’t broke, don’t fix it.
If the engine isn’t having any problems, why spend all the money to repair something that isn’t broken?
What type of oil are you using in the engine? BMW requires special oil for that engine. Here is the note from my Online Product Application Guide – 2002 BMW M5 Product Application Guide
[i]Castrol high performance synthetic oils, Castrol Formula RS SAE 10W-60 also called Castrol TWS Motorsport SAE 10W-60 Synthetic oil part no. 07 51 0 009 420 are the only BMW
approved products for a complete engine oil change. If in between oil changes these Castrol high performance synthetic oils with a viscosity of 10W-60 should be unavailable,
engine oil with an API rating of SJ/CF or better and a viscosity of SAE 10W-60, SAE 10W-40, SAE 5W-50 or SAE 10W-50 may be used in small amounts for top-up only.[/i]
I also strongly recommend you stick with original quality Mann oil filters. My product application guide lists the Mann oil filter part number as –> HU9384x
If you really want to check the internal condition of the engine, the best way to do this is by having a laboratory oil analysis done. This will tell you what’s really going on and can save you scads of money!
I hope this helps you out.
