Una calda, una rece, de la clienti americani.Oricum pretul din state de 9-10$/litru nu prea concureaza cu pretul din Europa.E mult prea mare si cred eu nejustificat.
Calda:
I have read a great deal about Amsoil, Mobil One and Castrol. I've been using Castrol in my cars since the early 1970's switching to Syntec in the early 1990's. Having owner 4 airplanes and a number of boats I perform most of the maintenance myself. Back in the 1990's Mobil One got in a world of trouble with their aircraft oil whereas the teflon would separate and attach to the interior of the engine causing blockages for the oil to circulate properly. It was enough of a problem and left a bad taste in my mouth with that Brand and the way the matter was handled. I've always had good luck with Castrol products and never had a reason to look elsewhere for a different Brand. However, after reading several independent laboratory results regarding the best motor oils and their properties, i.e.; maintaining viscosity, lubricity, oil breakdown, shearing and eventual change in the SAE measure(10W/40 in 4K miles to < 5W-10W/30) AMSOIL always fared the best overall.
So recently I changed the transmission and final drive fluids to AMSOIL Severe Gear Fluid 75W-90. Also I changed the motor oil to 20W/50 AMSOIL Synthetic. Immediately the gear shifting was smoother and w/o problems downshifting into first gear. Over the 500 miles I noticed the engine run much smoother and a bit quieter along with cooler. The digital oil temp gauge remains 1 bar below where it has always settled. And the most surprising change is the motor now always starts as soon as you hit the starter button, first time!
I am quite impressed and have sent out the prior oil for testing and will after 3K miles do the same with the AMSOIL to compare the lab results. I will also be using AMSOIL in our 3 cars (incl. VW TDI Diesel) along with my kids 4 dirt bikes and JD lawn tractor.
I highly recommend that you try AMSOIL, especially if you care enough to use the best! I've always said;" Oil is cheap, Engines are not!"

Rece

Amsoil has earned its reputation and in many circles and web conversations it is referred to as "Scamsoil" and rightly so. Let me say this Amsoil is Not a bad product. It is just over hyped so much that the consumer gets caught up in a sale of snake oil. The truth is... Amsoil if a good product..but the price you are paying is ridiculous for what you are receiving. It is truly no better than other off the shelf name brand synthetic motor oils. If it truly was ....EVERY exotic, luxury down to the cheapest cars made would be recommending it! Literally to save THEMSELVES money. NOT 1 manufacturer recommends Amsoil. Look it up on the net. Virgin oil samples ARE what oils are made of...it's really not hard to find out that it is just another synthetic motor oil. Its just like any other quality synthetic motor oil! Except, that it is twice as high! It's a joke...buy a name brand API certified oil and follow the manufactures recommended oil change intervals. There is no "Magic" oil. Don't waste your money on snake oil.



No comment.
Real motors don't need forced induction
Who needs a turbo when you have a stupidly quick,naturally aspirated motor?

Nobody's perfect but if you drive a MINI Cooper R50 with Chrysler engine ,you're pretty damn close

Salut! Sunt si eu posesor al unui Mini Cooper R50 2005
Automat 116 cai Benzina
Acum 3 luni am facut schimbul de ulei la motor, nu stiu ce ulei avea inainte. Am fost la service si am schimbat uleiul, cu 5w40 Castrol C3. La cateva zile dupa schimbul de ulei,se aprinde becul de la ulei , dar nu imediat de la pornirea motorului, ci dupa 10 min, dupa ce se incalzeste. In mers se stinge, la semafor cand opresc se aprinde.nu pierde ulei, ma uit zilnic.
Ma puteti ajuta? Multumesc!

Salut,
Presiunea uleiului la ralanti trebuire sa fie minimum 0,25 barr, iar la 3000 rot/min, minimum 1,7 barr. ambele cu motorul ajuns la temperatura de regim functionare(90 grd C).
Cauze:
-traductor presiune ulei defect( se masoara/verifica), se schimba;
-nivel scazut ulei in baie;
-presiune scazuta de ulei datorata unei probleme tehnice in motor (pompa ulei,etc. )
-calitate slaba ulei(isi pierde vascozitatea la temperatura de regim);
Cel mai simpla cale este sa masori presiunea de ulei cu un manometru, iar daca este in limite, atunci ai probleme cu traductorul presiune ulei. Daca presiunea este scazuta, schimbi uleiul cu unul de calitate, dar poti sa ai surprize si sa trebuiasca sa verifici pompa de ulei sau alte componente. Daca tot schimbi uleiul, da baia jos, verifici si pompa si faci o curatenie generala. Filtrul de ulei este schimbat?

Numai bine,

Chestia este ca, inainte sa schimb uleiul nu se aprindea. Da am schimbat si filtrul!
Am sa duc masina la service sa vedem ce are exact! Multumesc!!!

Este ok uleiul ca si vascozitate? Scuze, nu ma pricep! Multumesc!

Cu cit este mai mica cifra in fata literei "w" (SAE), cu atit este mai mica viscozitatea uleiului la temperatura scazuta si, respectiv, pornirea la rece a motorului este mai usoara. Cu cit este mai mare cifra care se afla dupa 'W' (SAE), cu atit este mai mare viscozitatea uleiului la temperatura ridicata si asigura ungerea motorului pe timp de vara/canicula. La tine este 40, deci ar trebui sa aigure o ungere buna/presiune la temperatura ridicata, dar ceva se intampla.... Eu oricum nu mai cumpar de multi ani uleiuri care se vand in RO :mrgreen:

Da, este ciudat, e posibil sa se intample ceva daca mai merg cu ea asa? Multumesc!

Dupa cum stim, lampa rosie in bord inseamna avarie, motorul se opreste si nu se mai continua deplasarea. Rezolva cat mai repede :!:
