Mobil 1 Questions & Answers

What make, model and year car do you have troy? Bit more info would be helpful bud. :-)

Hi Leo, does your Crown have the 1MZ-FE 3.0L V6 engine in it? If so, the Mobil 1 DataTek website recommends Mobil 1 5W-30 or Mobil Super 2000 X2 10W-40.

Choosing the correct oil viscosity really depends on the climate you live in. There are lots of good websites out there explaining this. If your car is a Japanese import, then the manual will probably state a quite thin oil viscosity, similar to the northern states of USA, as it's quite cold in these regions.

In warmer climates eg. in the Southern hemisphere between the Equator and the Tropic of Capricorn, then you would want to select a slightly higher viscosity of oil, e.g. Mobil 1 5W-30 or 5W-50 if it's really warm.

If you have oil leaks in your engine though, then proper repairs and regular preventative maintenance of your engine really needs to be carried out on a regular basis. Regular engine oil changes with synthetic engine oil (preferably from new), = a happy healthy engine. Hope this helps.

Thanks, points taken. I think it would help me to handle the issue

Yep. Should be fine Raj.

If oil comes out black in a diesel then the detergent pack is doing its job to keep your engine clean. Track down some Motul engine clean/flush rather than wasting your time running through a cheaper syn. It's a detergent based flush rather than solvent like the cheap brands, it works very well.
Have you thought about getting a UOA (Used Oil Analisys) done? That's the only way you're going to know what's really going on inside your engine & how well the oil is holding up. Anything else is speculation. Depending on the resultsite you see 5W40 may not be needed until around 200K.
I think you're wise not running 30K intervals, 20K is a stretch IMO but obviously working fine for you.

Yes, exactly what I think

Hi Peter080

This is my opinion only and as such; open to variation by yourself and others. 30,000 is a LOT of kilometres - if it was my vehicle I would be cutting that in half or even down to 10,000 km. Synthetic engine oil is so cheap when compared to the cost of parts and labour at pull-downs? I mean - it could only benefit the engine and extend the life. It may even assist with that timing chain noise (if the tensioner is hydraulic).

G'day Warren, was just looking at your question. I found some info from the internet for you. From the Mobil Lubricant Recommendations, the only Mobil oil suitable for your PX Ford Ranger is Mobil Super™ 3000 X1 Formula FE 5W-30.

Type this link in your address bar to see the specs from the Mobil website for this oil:

Select Commercial Vehicles - Light/Medium & 4WD, and select your make and model.
Should give you all the POL's you require. Works in the same format when you search on the Castrol web site as well. If your unsure or in doubt, I would consult your local Ford dealer. Good Luck!
Nick.

From what you have asked i'm getting you do approx 1000 km a month
and use 5w50 oil, you haven't however, said what engine it is, is it turbo or NA, what vehicle, driving habits, or stated your manufacturers recommended servicing intervals.
without knowing any information like that it would be hard to give you any kind of advice.
however, it seems like a large spread of oil weights you are using, most modern engines seem to use around a 10w30 or 0w30 for less oil drag on the lighter piston rings they use nowadays,
so in conclusion, we'd need more information.

G'day Dindo,
First of all, good on you for using Mobil 1. I have been using Mobil 1 for the last ten years, & have been very impressed with the cleanliness of the engines and of the oil. My vehicles run cleaner, smoother and quieter by using Mobil 1. I personally won't use anything else!
The chap above has a point, but you will find that both your vehicles manufacturer and Mobil 1 will recommend changing your oil and filter at the vehicle's recommended servicing schedules,
There has been a lot of private research done, which you can find on the net, particularly wrt Mobil 1, and how long it will last before the oil breaks down and requires changing.
Probably the true way of testing would be of oil sampling through a laboratory oil analysis. Mobil 1 did it when Mark Skaife drove the HSV Maloo around oz.
If it were me, I'd follow the service schedule regardless of the oil type, e.g. if you have a Toyota, then it's usually 6 months or 10,000kms, which ever comes first. It's your call.
