I imagine Manufacturers put the cheapest GO TO oil in their New Cars ..just as they do with the TYRES...do YOU SERIOUSLY BELIEVE the engine will BLOW UP if you use a superior synthetic in it.... ::) :banghead: :bang: :shuffle:

Sorry sir I have been forever tainted by the VW 1.8T and the "turbo turds" fiasco.  Dealer supplied bulk dino in 5W-30 was cooking off around the turbo. These carbon deposits would clog the oil intake and boom! Not to be confused with a sludging problem. I avaoided the whole issue by running Mobil 0W-40 and doing it myself. It also fed into my distrust of dealers.


In a forced induction engine you are nuts to run anything but the top shelf oil. With my current daily drivers I am running good synthetics for a different reason in that the oil change intervals for these are about once per year. I have no trouble extending the intervals to that but for the extra $10/year I will buy a little insurance by going with a manufacturers best product.

YOU ARE proving my point.......................why the "Sorry Sir" comment ???..my post says use better tyres and oil than that originally put on and in the new car you buy..................it won't affect your warranty and the car will ride better and the engine last longer...........hell i don't know why new cars don't come with Top of the line tyres and oil from THE GET GO!!!! prolly cost pennies extra per vehicle... :light: :banghead: :bang: :banana: :thumbup: :think:

I agree with you Saf.   But those pennies per vehicle add up for the bean counters.

I think that, with exceptions of course , that the OEM tires are rated to last a 3 year lease plus being in good enough condition after 60-70,000 kms to pass end of lease inspection.   And of course they have to be all-season so the buyers don't complain about the expense of snow tires... for MOST of the population of North America all-seasons will get them through anyway.

As for the oil.  Is coking with turbo engines a problem any more?   Now the turbos have water jackets for cooling and even non-synthetic oil is very good. I wonder...

Coking was a problem for the Passat 1.8T and A4 IIRC. The N-S engine oreientation made the sump smaller (3.5L?) Dealer dino bulk oil was coking. The funny thing was the bulk oil didn't even meet VW specs. I quizzed the VW shop about it when my Passat was new and got blank stares in response.   ::) I brought in my own Mobil 0W-40. If I ran the V70R hard I was careful to give her a little cool down. The premium oil was insurance because my wife had a heavy foot and I am sure a cool down never crossed her mind.. ;D

AS: It is German, so I guess group 4, whatever that means. Do you think it may void manuf. warranty if one uses oil other than marked on the cap?

Not if the dealer puts it in.  It gets entered into the Toyota system simply as an oil and filter service and that's all that is necessary.  If it's done elsewhere and you are relying on "receipts" then warranty work would be discretionary relating to the internals of the motor.

However, I think it's best to stick to an 0W20 or 0W30 synthetic rather than say a 5W30 for warranty purposes.

I bought a case of this 0W30 August/2011 for $5.68 litre plus tax.

Not bad at all. Whereabout?

If you buy a top of the line car it comes with top of the line tires.  If you buy a value-priced car, it comes with value-priced tires.  No need for head-banging, just pay the price.

I'm sure people who buy a value priced Hyundai would be quite upset if it cost them $1600 to replace the OE tires.  Most people just want the cheapest and longest lasting tires they can find and won't pay anywhere near premium pricing.

Again the XD3 is similar to the German Castrol 0w-30. They are both 0w-38'S. I think XD-3 is GC's doppelganger.

0W-40 has been discontinued no?

Ya Vole

I was putting that stuff in my 944S2 which has only 35k miles on a factory 968 block, but after it was discontinued, I really wasn't to keen on buying other Group 4 oils at twice the price and I wasn't going to take it up the *ss with the Mobil Group 3s, so I decided to come down to earth and use 20W50 Castrol dino and leaving it running 5 minutes when cold start up.

I didn't say $1600 extra, but they certainly can be up to $1600 to replace them.
Dunlop    Sport 01 DSST    215/40R18    85Y    $427.00
Non run-flat's would be more around the $1300+ mark.

I don't think I have to provide proof that top of the line car  have the best tires, just look under a new Corvette ZR-1, Mustang Boss, Porsche 911GT3, etc, you won't find  Kumho all-seasons.

But yeah, I know what you mean, some OE tires leave a lot to be desired in the performance or longevity department, sometimes it's just people having different priorities than the tires were designed to provide, sometimes it's concessions made to auto manufacturers needs to meet CAFE ratings and budgets and you end up with tires nobody really likes, especially in lower end cars.

Leave you Kum ho's in the tyre thread  :rofl2:

BTW My Sonata came with LRR great quality Michelins. So I don't think it is a big difference in wholesale price for car makers to use better tires.

On the current crop of Foresters with the new boxer engine they call for 0-20 synthetic as well. Had first change on ours last weekend as was caught off guard when they told me the price. :o

I thought 0W20 was synthetic only as there is no way to make 0W20 from pure dino juice.

correct.  In my early post I meant 5W20 Dino bulk.  We now have 0W20 (synthetic) in bulk and finally got rid of the bottles although still stock them if customer needs just one or two.
