What was particularly important was the lack of additive restrictions to oil. In a standard car, oil burning in the engine is a symptom of a problem. Either the piston rings have degraded and are allowing oil around the piston and into the combustion chamber, or the valve seals have perished and oil is leaking directly onto the piston head. The engine will continue to run as long as it is kept topped up with oil, but as oil is not as combustible as fuel it is not ideally wanted in the chamber - and should be doing its job of lubricating the engine instead.
Fixing it is necessary if you want to pass your next MOT, and the environment will thank for preventing the blue puffs of smoke from your exhaust. These additives can provide a host of benefits, namely boosting combustion and delaying ignition within the chamber.
One method understood is the addition of second set of injectors at the bottom of the cylinders - below the pistons and just above the crank shaft — which sprays a mist of oil onto the underside of the pistons. With a full-service oil change, you'll receive a point inspection and an oil filter change.

Piston ring-pack deposits can sharply reduce ring movement and flexing. Likewise, ring movement can greatly influence where deposits form and the lubricant motion transport within the ring-pack. This ring motion defines the residence time of the lubricant in the ring-pack, which in turn affects the rate of lubricant degradation and where deposits will form see Figure 2.
Ring-pack temperatures can range from degrees C. Collectively, these conditions can accelerate piston-ring-liner PRL wear, impair combustion efficiency, increase blow-by and reduce oil economy more oil consumption. One way this happens is through carbon jacking. In this phenomenon, carbon buildup occurs in the ring grooves fed by soot and oil degradation products. The corresponding ring movement restriction increases wear, blow-by and oil consumption with the rhythm of the piston.
Figure 2. The sequence of piston ring-pack deposit formation. As much as 17 percent of total oil consumption is associated with liner wall evaporation. The more distorted out-of-round and rough surface finish the cylinder liner, the more oil film that will remain on the liner after the power stroke.
High liner surface temperatures degrees C will cause a loss of this oil by misting and evaporation. Light oil molecules are more prone to evaporation. Not all oils of the same viscosity are equal from the standpoint of volatility risk of evaporative loss.
Some lubricants may exhibit as much as a percent greater loss from volatility than others. Of course, temperature plays a key role.
A low liner temperature translates to a low evaporation rate. Liner temperature is influenced by load, combustion efficiency and cooling. Approximately 74 percent of vaporization occurs during intake and compression strokes no speed effects have been found.
Ovaloid cylinder bores are usually caused by machining issues as well as thermal and pressure distortions. Piston rings can conform to out-of-roundness cylinders to a certain extent. Oil mist is carried with reverse blow-by gases into the combustion chamber and outward with the exhaust. As a result, too much oil is left on the cylinder wall that then can move toward the compression rings or remain adherent to the liner, increasing oil loss through misting and evaporation.
As engines age and wear, they become greater consumers of crankcase oil. Solid contaminants combined with soot and other oil suspensions influence engine wear, deposits and oil economy oil consumption rate. When oil is consumed, it enters the combustion chamber, burns with the fuel and is pushed out with exhaust gases as particles and volatile hydrocarbons. Fresh new lubricants have more volatile light-end molecules and are more prone to hydrocarbon emissions. As the oil ages, the hydrocarbon emission levels off but can pick up again if the oil becomes contaminated with fuel fuel dilution , such as from short run times or long idles.
However, in general, the service life of the oil has no significant influence on carbon monoxide and nitric-oxide emissions. The level of exhaust emissions can increase considerably over time, corresponding to engine wear and deposit formation. This leads not only to greater exhaust particulates but also to a higher percentage that are hydrocarbon, which is a byproduct of oil consumption. It has been observed that lubricating oil is a significant contributor to the particulate emissions signature as the engine ages, especially with diesel engines.
This, in large part, is accomplished only by controlling combustion efficiency, wear and deposits especially through good lubrication and filtration practices. These ozone precursors also lead to smog when exposed to hydrocarbon gases and sunlight. The second salesman very polite and friendly and sold me the car in half hour. David Rojas was my service representative, he far exceeded my expectations. He found another recall on my truck, and took care of that.
He was able to get me a loaner car during the repair, which made things a lot easier for me. It was so nice walking in for service and everything going smooth. Appt was set and the person I dealt with at the dealership was very professional and informative. I was able to get a ride back home from their ride service and I was contacted throughout the day with updates. A full printout was given to me on the findings concerning the issue. Overall, a very pleasant experience and I would definitely go back again.
My last experience with the dealership was horrendous. This time it was beautiful from start to finish. I have leased from you for over 20 years. After my experience I almost terminated all contact ,but felt that I would try one more time to see if anything could be rectified. He had explained every move to me and treated me like an educated person. I had had to turn in my lease with First Toyato purchase for us.
Bryan Gonlazez was very attentive to our needs and answered all questions we had. I was bit disappointed when we test drove a vehicle, liked it and wanted to purchase only to find out it was sold. Bryan searched and found an almost identical vehicle for us to purchase. We financed the vehicle and that process was good but a bit lengthy.
We live in NH so Bryan was very accommodating to our schedule to meet us for registration and delivery.
He was certain to be sure all of our questions were answered and if Very pleased with my car-buying experience at Ira Toyota. Sales and finance staff were professional and easy to deal with.
Shout out to my salesperson, Jason Dick, who went above and beyond to get me the exact car I wanted even sooner than expected. Straightforward process for buying a used car. Let them know the car I wanted and they reserved it for me. Would recommend. My salesman John Arena was super knowledgeable.
I highly recommend him. Everyone I worked with during this process of purchasing my first new car was so friendly and helpful. Aiman the car salesman and Virgilio the finance manager were amazing! The car is amazing and everything I wanted. The process was smooth and I left very satisfied with my new car! Appointment at Noon, noting a mile road trip I was taking with my young children immediately following this repair.
It took 5. The service manager Danny Morales was extremely pleasant and helpful! Upon driving, I heard loud scraping noises coming from that same wheel.
Returned to IRA, but service was closed. Finally, unable to repair Easy online appointment and able to reschedule for earlier time. Quick service and comfortable waiting room. Service Advisor Matt Buonomo was very approachable and helpful in getting my car serviced within my time frame, which was a little tight. I feel my 2 yr old Prius is being serviced appropriately. Love the precertied program, third time I've used.
Our service advisor Nate Brungot was very helpful in our car service. Nate understood when I shared with him that we wanted to delay some of the service suggestions. Thank you Nate. Great service polite and organized honest people. Pricing was reasonable. Auto technician was great explained everything in detail to me was very helpful. Matt Buomono was excellent in providing service. I was greeted promptly. Everything that was to be done was explained in a warm and friendly manner.
When some other milage related issues came up, those too were explained and options put forward. As always courteous and experienced technicians. Very nice place to sit and read and wait for your vehicle I recommend it highly. Thank you as always. My experience was a 5 star one from beginning to end. The product is exceptional and the crew from sales to service truly professional throughout. I was impressed with how approachable and professional everyone was. They made the buying process much easier than I expected it to be.
Everyone was prompt and thorough. As always they were polite, organized and honest. Work was done timely and communication was great. The customer care was great there was two of them so pleasant and sweet. They both had patience, had my mother in law with me and she was chatting up a storm with one them- he just had a lot of patience. Very nice service we were out of there in an hour, definitely going to Danvers ma fir all service check ups for now. Our car had a problem with its tires; loud humming at certain speeds.
We were treated fairly and the service rep was professional and pleasant. Waiting room area is starting to look tired. Bringing in a car for a 30k check up raises considerable apprehension. The parts that are beginning to wear out, the cost and god knows what, but this is a Toyota, driven and maintained reasonably well. This is a top rate dealer with a service department that makes the procedure as quick and smooth as possible.
The usual friendly, professional service I have become accustomed to receiving at Toyota over the years. A perfect visit, fast, efficient and friendly staff made my service visit a breeze and on time. They totally saved us on a Saturday before we left for a trip when no other dealership would. Great service people from the moment I called to the check in and service. Ira's service department is superb.
These guys were quick with updates and helped make sure the issue wasb flawlessly resolved. You have a good service but today when I got my car back after being in the shop for couple days getting fixed it was really dirty from inside especially the seats. David was so helpful and able to squeeze me in even though I was running late. Please give him the credit he deserves for great service!
Clean comfortable waiting area. We have bought 4 cars from Ira. Great customer service and attention to details. Costs are reasonable. No hard upsells. The facility was very clean and freeflowing. Over all it was a great experience. Competent, polite professional and delivered in less time then anticipated! I will be a repeat customer, heck, I already am.
Great service Rest communication- detailed explanation of job completed Service manager was polite and quick to respond to text and email. A little confusion on using Lyft. I am always happy with the service at this location.
