I think you have to though to keep your warrantee, even though, mine is a US car.

Since I have been using Royal Purple (I get it at Lordco) for the last 6 years, I thought I would contact RP to ask a few questions. The reply is below..........

The RP guy says he can be emailed, but because of the correspondance he has to handle every day from people like us, he doesn't always guarantee an answer right away.

Anyway, maybe this will answer some questions. Bear in mind that the opinions are from the seller, but since I'm a trusting soul, I have to believe that a reputable company like RP would not recommend anything that would hurt an engine, or their reputation.

I have not been using HPS because I have not seen it locally, but I will look for it for my next change. (I do the work myself) I follow Honda's reccomendations for dino oil. Can't go wrong there.

Dave

Subject: 2005 Honda S2000 recommendations, and drain intervals (in kilometers)
Good morning Dave,

For your 2005 Honda 2.2L 4 cylinder S2000 we recommend the following:

Engine Oil: Royal Purple SAE 10W-30 (part #01130, quart bottle) or for a significant upgrade in performance and protection Royal Purple HPS 10W-30 (part #31130, quart bottle); 5.1 quarts

Engine Oil filter: Royal Purple Extended Life Synthetic Oil filter (part #10-2808).(available at most Pep Boys and from many online sellers);

Manual Trans: Royal Purple HPS 5W-30(part #31530, quart bottle) or Royal Purple XPR 5W-30(part #01021, quart bottle); 1.6 quarts;

Differential: Royal Purple Max Gear 75W-90 (part #01300, quart bottle); 0.8 quarts;

Power steering: Royal Purple Max EZ (part #01326, 12- oz bottle);


Gasoline engine drain intervals:
For engine oil in street driven passenger car/light truck gasoline engines that are mechanically sound, and stock or mildly modified, the interval is up to 19,300 Kilometers(12,000 miles) or one year, whichever comes first.

Depending on how many times time you have previously put a high-quality synthetic motor oil in your engine, we recommend you stay with the manufacturer's recommended interval for two oil and filter changes. This is generally 4,800 to 9,600 Kilometers.

If you have done this with another high quality synthetic, or if you have another car that has very low usage (new or almost new car), the oil change interval can immediately be extended to 2x to 3x the recommended factory interval up to a very safe extended interval of up to 19,300 Kilometers or 1 year.

We recommend changing the engine oil filter during the extended oil interval using a high-quality filter. If the filter manufacturer gives change interval guidance, feel free to use that. Otherwise, if running the oil to 19,300 Kilometers, change the filter and top off the oil level at 6,400 Kilometers and 12,800 Kilometers. If you run the oil for up to 16,000 Kilometers, a single filter change at 8,000 Kilometers will be sufficient.

If you are using a Royal Purple extended life synthetic oil filter it will go the full distance of 19,300 kilometers. (available at most Pep Boys and also from many online sellers).

If you put less than 9,600 Kilometers a year on your vehicle, we recommend changing engine oil and filter once per year.

Whenever you change the oil filter, but not the oil, be sure to top off the oil level to make up for oil lost with the filter change. If running the RP oil filter, check your fluid level occasionally because all engine use some oil.

The 'short' initial oil change interval is to ensure that your engine is relatively clean before going to the extended interval. Many conventional oils and lower quality 'synthetics' tend to form deposits inside engines, and in diesels, leave soot build-up. The natural detergent action of Royal Purple's superior quality base oils tend to clean these deposits and dirty up the oil quickly. After the first two oil changes with Royal Purple, the bulk of the gunk should be gone.

Due to HPS being a relatively new product your local stores will likely not have HPS on the shelves. However a special order can be done at your local NAPA and O’Reilly’s.

HPS oils are definitely available on line and shipping at the following performance outlets:
