You know those Oil "temp" charts were common in N America before all the mfgs reduced the tolerances in engines and thus "spec'd" them so we could run 0W-20 oils. Or did they just delete that manual page with the Ambient temp 'thick' oil chart? Hmmmmm?

The main reason for speccing thinner oils in the US is because of a federal requirement that manufacturers specify in the owner's manuals that weight of oil used when the window sticker fuel mileage numbers were obtained. As far as specifying closer tolerances, or for that matter, clearances, I doubt that they have changed very much in the last 60 years. I do know, that Chevrolet, several years ago, quit matching their piston tolerances to their engine block cylinder tolerances, saving money and leading to many complaints of engine knocking when the clearances stacked up too much in the wrong way.

Yes, I've had many vehicles that had charts. It's just been sad to see them go. As for your last point, that's probably quite right, since some of the manuals don't seem to have been edited properly to reflect only one grade and API/ILSAC certification. My Infiniti manual recommends, in one place, choosing viscosity based on ambient temperatures, then elsewhere speaks of 5w-30 SM/GF-4 as recommended, and in other places required.

You mean to tell me there are no AutoZone or PepBoys stores in the middle of a desert in Saudi Arabia or in Bahrain??? Now, who would have thunk it? LOL MAKamal, welcome to BITOG! Nice car!

I agree, but that doesn't mean to go thicker than necessary just because of CAFE. In my 3.7 L, the same engine family as that of the original poster, the engine will go into limp mode if the oil gets too hot. If the oil is thicker, that's good for the oil itself if it gets hot; however, a thicker oil WILL run hotter, and will simply cause the engine to go into limp mode sooner. A better oil cooler is the solution in this case, not thicker oil.

Hi, MAKamal: I will put in my two cents worth of advice here. I think the main issue is the dust in Bahrain, so the oil filter should be changed with the oil, and the air filter serviced regularly. With such frequent changes an oil filter like the Bosch Premium or its equivalent is good and economical. That region almost never sees low temperatures, so oils with higher weight values are OK. There is a region in California with a similar climate; and that is the northern section of Death Valley around Scotty's Castle. But Bahrain has no high elevations. What the dealer is putting in is fine, but when out of warranty for this climate I personally would use a 10W-40. But the Shell Helix Ultra 5W-40 (Approved by Porsche and Ferrari) looks good as presumably it can take high temperatures.

I would assume that the engine would go into limp mode if the oil got too hot - thus, you don't want too thick of an oil in the first place, since it will just run hotter anyhow. If it were me, I'd stick with the M1 0w-40 or something 5w-30 SM like the Fuchs TITAN GT1 Pro Flex 5W-30 or LIQUI MOLY Longtime High Tech 5W-30. Why is the Castrol Magnetech in 10w-30 all SM or better, while the 5w-30 is SL in your location?
Garak Thank you for your input. About the Castrol Magnatec 5w-30 I doubt this is available in our market but I got the data from the net, let us ignore this one. Yes the temperature here is getting really hot as I mentioned in my first post, but as the car manual recommendation it's preferred to use 5w-30, but there is an additional statement which is not shown on the attached shot, "if 5w-30 is not available, select the viscosity from the chart that is suitable for the outside temp". The M1 0w-40 will cost me about $68 for 4L and I see it is a bit pricey for 5000km oil change. Many Maxima owners in my region are using Fuchs oils and they are happy with it, many of them are using 10w-30 grade, but I have two critical questions and really need the answer, the Fuchs TITAN GT1 Pro Flex 5W-30 is available in our market but the specs say that this oil is Specially developed for BMW, Mercedes-Benz and Opel vehicles with exhaust after treatment and turbocharger. 1. Is this oil safe to be used in my Maxima VQ35 engine? 2. Can this oil tolerate for 5000KM (3000M) intervals? Will the 5w-30 get sheared quickly? Here you can find the Fuchs Products data http://www.fuchs.com.au/categories.asp?cID=9&c=162634 Please send your answer ASAP as I am going to change the oil two days later. Regards,

Looking at the link you provided, I see very little wrong with the Pro Flex 5w-30. It meets a variety of decent specifications. It shows it as meeting API SM, but nothing about ILSAC. The latter is my only concern. Will it be an issue? That's hard to say. Your manual pages indicate that an ILSAC rating is recommended but not required, so if a warranty issue were to arise, who knows what Nissan would do? There's nothing wrong with the 10w-30 you mentioned, either. It meets both the API and ILSAC specifications. In your weather, I'd have no hesitation in using a 10w-30, particularly that one meeting those specifications. As for shearing and what it really means in your application, that's hard to say. For the VQ engines, I've seen very expensive oils shear, and some "lesser" oils exhibit no shear. The durability of these engines isn't in question, anyhow, so perhaps shear might not be a huge issue here, except on paper.

If so I would call that whopper of an engineering mistake.

With heat and dust: 'Thicker oil is better', changing frequently is important since there is sand or dirt, Synthetic is my first choice, but not required, Cost and availability are legitimate factors I might want to allow for cost , but more so the availability of the oil... The best choice might be the one that you can buy when its time to change I would consider any of the oils below: Castrol Magnatec 10W-40 Castrol EDGE 5W-40 Mobil 1 0W-40 LIQUI MOLY Synthoil High Tech 5W-40 Shell Helix Ultra 5W-40 Fuchs TITAN SUPERSYN 5W-40 or even the dealer's conventional oil Mobil 20W-50 If sand, dirt, and short trips are a big concern and they probably are... then maybe low cost is better and changing oil every 3000 miles or even less is as important as the viscosity and brand , synthetic or conventional etc. Oil analysis could help determine if dirt is really getting into the engine and an issue... if there is oil analysis in your region Best of luck with your new car!

Anyone besides me notice the note saying 5W-20 is not suitable for sustained high speed driving? 'Spose Honda, Toyota, Ford et al know this???

When they say "sustained high speed driving" they probably mean something like the Autobahn. What we have in the US by comparison is sustained grandma driving, so no need to worry. smile

Thank you guys for coming in. I found that most of the European Oils meet API Certificate but not ILSAC unlike American Oils. Since my car manual recommends API and ILSAC Certificates I was recommended by friends to go for Motorcraft Premium Synthetic Blend Oil and it's available in 5W-30 and 10W-30 and other grades too and can be easily bought from Ford/Mercury Agent for $3.17/quart also found positive talks about it in this forum. Motorcraft 5W-30 Premium Synthetic Blend Oil properties: SAE Grade 5W-30 API Service GF-5/SN Specific [email protected] 60°F (15.6°C) 0.860 Density, lb/gal 7.17 Flash Point, COC, °C (°F) 206 (402) Viscosity: cSt @ 100°C 10.8 cSt @ 40°C 65 cP @ -30°C 6,300 Viscosity Index 163 Pour Point, °C (°F) <-42 (<-44) MOTORCRAFT® 5W-30 PREMIUM SYNTHETIC BLEND MOTOR OIL Motorcraft 10W-30 Premium Synthetic Blend Oil properties: SAE Grade 10W-30 API Service GF-5/SN Specific [email protected] 60°F (15.6°C) 0.871 Density, lb/gal 7.25 Flash Point, COC, °C (°F) 224 (435) Viscosity: cSt @ 100°C 10.4 cSt @ 40°C 69 cP @ -30°C 5,900 Viscosity Index 157 Pour Point, °C (°F) <-42 (<-44) MOTORCRAFT® 10W-30 SYNTHETIC BLEND MOTOR OIL You guys can read the figures better than me, consider my car is yours which one you will choose from the above for 5000km (3000mile) OCI. Regards and many thanks again

Nissan knows that 5W-20 is closer to being a solvent than an oil.

Some might, but I haven't. I don't track or drive overly aggressively. If you ask me, though, it is an engineering mistake. My old Audi with a turbo had an oil cooler that was bigger than the radiator, and couldn't push the oil temperatures above 100 C, no matter how hard I pushed it, and that was with 15w-40 in it on a 34 C day.

For the OP's family of engines in North America, 5w-20 isn't recommended whatsoever. 5w-30 is it.

I say either would do the trick. It's pretty cool that you can get the Motorcraft oil there for that price. Grab whatever what's closest on the shelf, I suppose. I'd lean towards the 5w-30, with it being the recommended grade, but I'd use either here, even in Canada, in the summer. Interestingly enough, Infiniti of Canada pushes Mobil products (conventional and synthetics) at their dealers. Nonetheless, the Motorcraft is probably your best bet, meeting all recommended specifications at a very nice price.
