Hello everyone. I have a quick question about my next oil change for my 2uzfe equipped Toyota (4.7) v8. It is obviously a gasoline engine that operates in the USA with American fuel. May I use penzoil euro 5w30 in my tundra? I know it meets SN oil specs which is more than plenty for my 20+ year old engine, but is it compatible with USA gasoline standards? I’m sure there are better oils out there for my application, I currently use Quaker state 5w30 religiously, great oil for a great price, I live in north Illinois. I know the euro oil is fine for my tundra and I want to use it for its thicker tendencies as I run my truck hard in the summer, it’s a c3 rated oil which means it has a 3.5 or higher hst. Am I good to go? I don’t want to step up to a 40 weight or a light 40 weight like Quaker state 5w40 euro because I want the peace of mind of 5w30 going into a 5w30 specd engine. Sorry I’m not very educated on this topic so bear with me. I’m very interested in euro oils in general for their thicker tendencies and stout additives for euro oil standards. I also hear some euro oils are apparently not good for longer oil change intervals, not an issue with me as I run 4k oci with mainly city miles
 
A twenty year old Toyota, running a 5W30 that is API SN and ACEA (Euro) C3 sounds great to me. The Pennzoil Platinum Euro L 5W30 is a GTL based full synthetic, that also carries MB 229.51 which is a very tough standard to meet. That means HTHS at or above 3.5 cP, and Noack volatility at or below 10%. Very respectable.

The mid-SAPS Euro sequence C3 has an ash limit of 0.8% (SA), and a Phos limit of 700 to 900 ppm. Very similar to the typical modern day API / ILSAC oils, so it's safe for use with modern fuels over regular distances. Your doing an OCI of 4k miles, this is not a problem. I'm running a Euro 5W30 C3 oil right now, probably with the same or possibly lower quality fuel, and I plan to go 6k miles.
 
Where did you hear this? Many if not most European approvals have a long-drain requirement.
See that’s the impression I was under aswell, but I’ve seen a few comments on here that say they wouldn’t run some specific types of euro oil for long drains cause of low ash or saps whatever it’s called. Don’t quote me on that but I’m sure someone could chime in

To be honest there is some truth to what you say. Its all got to do with fuel quality and in particular sulphur levels in the fuel, which can form acids in the oil, and need a higher TBN (total base number) to counteract the acid buildup. As TBN went up, so too does the sulphated ash (SA%, SAPS) level.

In the old days of bad fuel with high sulphur levels, a long life Euro (ACEA) oil was a high SAPS oil (e.g A3/B4) with a TBN above 10, and a SAPS level above 1.0% SA.

Europe was the first to move to ultra low sulphur fuel. This meant TBN and SAPS levels could be reduced, this was good for the exhaust system, while keeping the OCI similar. ACEA C3 is a mid-SAPS Euro oil with the same HTHS & Noack & wear requirements of A3/B4, but built on a reduced TBN & SAPS additive package.

These C3 oils were fine in Europe with their low sulphur fuel. But move to Australia with higher sulphur content, and you had to either stop using C3 and start using A3/B4, or keep using C3 but significantly reduce your oil change interval (OCI).

Over the years more and more countries have reduced sulphur levels in fuel, and now they too can go longer OCI on C3. I believe that this recently includes most of North America (NA). Australia is down from the bad old days of Super Petrol (high octane leaded gas) containing 800 ppm sulphur. But we are not yet at the low European or NA levels.

What's the typical OCI recommendations for DI engines in Europe?

C3 Used to also be recommended for DI engines to help IVD. Does that still hold true? I haven't kept up with the recent theories.

Those 4.7s are very easy going motors for oil. I ran mostly PUP 5w30 in mine, but also ran regular Mobil1 and Maxlife 5w30. It towed a Jeep all over, did trail duty, winter and summer with a small lift and bigger tires. Had the DT headers, DT mid pipe and a full exhaust that I let sing everywhere. Even running 6k OCIs, the oil always looked like I could've put it right back in. Never had to worry about the oil, just the fuel tank that was empty every other gas station. That said, a Euro spec oil will absolutely spoil the 4.7 and id not be afraid to run an extended OCI.

Also, if you haven't seen it already:
 
The Pennzoil is a cut above Quaker State. Even the fine folks at SOPUS offices will tell you that.

Some (including myself) want a top-shelf oil for wear protection, cleanliness and engine clatter resistance insurance purposes. Its not about the money.

Most Toyota engines will get 250-300k on Supertech. I'm jealous and full of envy. How can a country like Korea (so close to Japan) sell junk engines, when Japan sell arguably the best.

I know - I know! One caters to the tight family budget crowd. Well, I'm not on a tight budget..... that's for sure. My wife's side of the family is loaded. 🤤

One more question, about to pick up my euro 5w30 (either penzoil or castrol), and my tundra sometimes will blow blue smoke out every other months from valve guide seals seepage, will euro oil kill my o2 sensors and CATS more than a regular oil?

What an awesome reply thanks for your effort

Pennzoil Euro 5w30 is a low SAPS oil so it’s actually better for your emissions system

I don't know. I don't think it holds up. I've yet to see a GDI engine that at some point does not have a carbon buildup issue. Oil can really only do so much. My preference for that is lowest Noack, highest solvency and oxidation resistance. I'm not sure if ash matters. It's been said HPL and Valvoline R&P can potentially clean them over time.
 
Cool, I’m a total noob and just realized that in the USA I should be using full saaps oils because of our sulpher content in our fuel. So basically my oil needs are HTHS 3.5 or higher, full saps.
 
Think I’m going to settle for some castrol 5w30 euro since it’s a3/b4 rated. I want to just use Quaker state euro 5w40 in the tundra since I use it in the Lexus, but I’m not comfortable with doing that at the moment. Want to stick with the 30wt grade even tho hths is more important than the claimed grade, but it’s just peace of mind

Skip the Euro oils and use a 5W30 high mileage oil. Valvoline makes good high mileage oil.
U.S. sulfur content in gasoline is no longer high and I think you're reading old info. The only time it might go high is when a refinery ask for a fuel waiver. You can look up EPA fuel waivers HERE.
